the total cost of leather purchased to make the football is $30.79.

The volume of a football can be calculated using the formula for the volume of a sphere:

V = (4/3)πr³

Where r is the radius

Given that the diameter of the football is 14 cm and  the radius is half of the diameter, so radius is 7 cm.

So, the volume of the football is:

V = (4/3)π(7 cm)³

= 1437.33 cm³

Now, we know that 3% of the leather is wasted,

so the amount of leather to make the football is:

(100% - 3%) = 97% of the total leather purchased.

Therefore, the amount of leather used to make the football is:

0.97 × 1437.33 cm³ = 1394.19 cm³

To find the total cost of the leather purchased, we need to know the cost of leather per square centimeter. Let's assume that the cost of leather including labor is $0.05 per square centimeter.

The surface area of a sphere can be calculated using the formula:

A = 4πr²

So, the surface area of the football is:

A = 4π(7 cm)²

= 615.75 cm²

the total cost of the leather:

Cost of leather = Cost per square centimeter × Surface area of the football

= $0.05/cm² × 615.75 cm²

= $30.79

What is a rectangular prism?

A right rectangular prism is a box-shaped object, that is, a 3-dimensional solid which has six rectangular faces. Rectangular prisms can also be oblique - leaning to one side - but the side faces are parallelograms, not rectangles. A right rectangular prism is also called a cuboid, box, or rectangular hexahedron. Moreover, "rectangular prism" and "right rectangular prism" are often used interchangeably.

The most common math problems related to this solid are of the type right rectangular prism calc find V or find A, where the letters stand for the Volume and Area, respectively. Let's see the necessary rectangular prism formula and learn how to solve those problems quickly and easily.

How do I find the volume of a rectangular prism?

The rectangular prism volume formula is:

volume = h × w × l,

where h is prism height, w is its width, and l is its length. To calculate the volume of a cardboard box:

Find the box length. For example, it can be equal to 18 in.

Determine its width. Let's say you measured 12 in.

Find out the rectangular prism height. Assume it's 15 in.

Calculate the cuboid volume. Using the rectangular prism volume formula above, we get volume = (18 × 12 × 15) in = 3240 in³.

How do I find the area of a rectangular prism?

The surface area of the cuboid consists of 6 faces - three pairs of parallel rectangles. To find the rectangular prism surface area, add the areas of all faces:

surface_area = 2 × (h × w) + 2 × (h × l) + 2 × (l × w) = 2 × (h × w + h × l + l × w),

where h is prism height, w is its width, and l is its length.

Let's see an example of how to solve the right rectangular prism calc - find A problem. We'll come back to our example with the box and calculate its surface area:

Calculate the rectangular prism surface area. First rectangle area is 15in × 12in = 180in², second 15in × 18in = 270in² and third one 18in × 12in = 216in². Add all three rectangles' areas - it's equal to 666 in² (what a number!) - and finally multiply by 2. The surface area of our cardboard box is 1332in².

Or save yourself some time and use our rectangular prism calculator.

Finally, let's attack the right rectangular prism calc find d (that is, the diagonal) type of problem.

How do I calculate the diagonal of a rectangular prism?

To determine the diagonal of a rectangular prism, apply the formula:

diagonal = √(l² + h² + w²)

where h is prism height, w is its width, and l is its length.

Do you have the feeling that you saw the formula before? Yes, that's possible because this equation resembles the famous one from the Pythagorean theorem.

If inversion be defined on K as a physical act of turning a member of K upside down. Then it will be the upside-down triangle.

consider the set K = (triangle, upside-down triangle, square, rectangle). Inversion is defined on K as the act of turning a member of K upside down.

To determine which shape is the triangle, follow these steps:
1. Identify the properties of each shape in set K:
  - Triangle: 3 sides and 3 angles
  - Upside-down triangle: same properties as a triangle, but inverted
  - Square: 4 sides, all equal in length, and 4 right angles
  - Rectangle: 4 sides, opposite sides equal in length, and 4 right angles
2. Analyze the effect of inversion on each shape:
  - Triangle: Inverting a triangle results in an upside-down triangle.
  - Upside-down triangle: Inverting an upside-down triangle results in a regular triangle.
  - Square: Inverting a square does not change its appearance.
  - Rectangle: Inverting a rectangle does not change its appearance.
3. Identify the shape that becomes a triangle after inversion:
  - The upside-down triangle becomes a regular triangle after inversion.
So, the shape in set K that corresponds to the triangle after applying inversion is the upside-down triangle.

Rolle’s Theorem can be applied to the closed interval.

What is the Rolle’s Theorem?

In essence, Rolle's theorem or Rolle's lemma argues that there must be at least one stationary point—a position where the first derivative is zero—between any two separate sites where a real-valued differentiable function achieves equal values. The theorem bears Michel Rolle's name.

Here, we have

Given: f(x) = -x² + 3x, [0,3]

We must determine whether Rolle’s Theorem can be applied to the closed interval.

f(x) is continuous in the closed interval  [0,3].

f(x) is differentiable in the open interval (0,3)

f(0) = 0 + 0 = 0

Rolle's theorem can be applied.

f'(x) = -2x + 3

f'(x) = 0

-2x + 3 = 0

3 = 2x

x = 2/3

2/3 lies inside the [0,3].

Hence, Rolle’s Theorem can be applied to the closed interval.

Answer: To obtain triangle A'B'C' from triangle ABC by reflection over the line y = 2, we reflect each point of the triangle over the line. This gives us:

A' = (A_x, 4 - A_y)

B' = (B_x, 4 - B_y)

C' = (C_x, 4 - C_y)

To obtain triangle A"B"C" from triangle A'B'C' by translation by the directed line segment from (0,0) to (3,2), we add the vector (3,2) to each point of the triangle. This gives us:

A" = (A'_x + 3, A'_y + 2) = (A_x + 3, 6 - A_y)

B" = (B'_x + 3, B'_y + 2) = (B_x + 3, 6 - B_y)

C" = (C'_x + 3, C'_y + 2) = (C_x + 3, 6 - C_y)

Therefore, the vertices of triangle A"B"C" are (A_x + 3, 6 - A_y), (B_x + 3, 6 - B_y), and (C_x + 3, 6 - C_y).

Step-by-step explanation:

Answer: We can simplify the expression by using the identity for the tangent of half an angle:

tan(x/2) = sin(x) / (1 + cos(x))

where x is the angle in radians. We can use this identity by setting x = 56° since 2*28°= 56°.

So, we have:

sin(28°) / (1 + cos(28°)) = tan(56°/2)

We know that 56°/2 = 28°, so we have:

tan(28°)

Therefore, the expression simplifies to a single trigonometric function:

tan(28°)

Step-by-step explanation:

Using properties of square,

a. Equation for total area = 2x² - 16x + 64

b. Area will be minimum for the value of x = 0

c. Minimum area will be 64cm².

With four equal sides, a square is a quadrilateral. There are numerous square-shaped objects in our immediate environment. The equal sides and 90° internal angles of each square form serve as indicators of its identity.

Total length of wire = 32cm.

Now side of one square is given as x.

Perimeter of big square will be = 4x.

Now perimeter of small square = 32- 4x.

Side of small square = (32-4x)/4

= 4(8-x)/4

= 8-x

Area of big square = x × x

= x².

Area of small square = (8-x) ².

Now Total area, A(x) = x² + (8-x) ²

= x² + 64 + x² - 16x

= 2x² - 16x + 64

The side length that will minimize the area will be, x = 0.

Minimum area of the total figure will be = 64cm²
