A Circle is a closed plane geometric shape figure. The diameter of a circle is the longest chord of a circle. The radius drawn perpendicular to the chord bisects the chord. A Circle is always lie at an equal distance from a center point. Circles having different radius are similar.

The area of a circle is pi times the radius squared. The unit of area of circle is square units.

[tex]\longrightarrow Area_{(circle)} = \pi r^2[/tex]

Here, r is the radius of the circle.

We are asked to find the area of the circle in terms of pi if the diameter is 7 inches.

We know that, the diameter is twice the length of the radius of a circle. Therefore;

Now the area of circle will be:

[tex]\implies Area_{(circle)} = \pi r^2[/tex]

[tex]\implies Area_{(circle)} = \pi (3.5)^2[/tex]

[tex]\implies Area_{(circle)} = 12.25 \pi[/tex]

Hence, the area of the given circle is 12.25π square inches.

Answer:

Step-by-step explanation:

In the question we are given that diameter of circle is of 7 inches . And we have asked to find the area of the circle in term of pi ( π ) .

For finding area of circle we must have to know that what is the formula for finding area of circle. So :

[tex] \qquad \qquad \: \red{\underline{\red{ \boxed{ \frak{Area \: of \: Circle = \pi r {}^{2} }}}}}[/tex]

Where ,

Solution : -

As in the question we are given length of diameter . So for finding area we need to find the radius of circle .

We know that diameter of circle is two times its radius or ,

[tex] \qquad \: \rm {Diameter = 2 × Radius }[/tex]

So for radius we are dividing both side with 2 :

[tex]\qquad \: \rm { \dfrac{Diameter}{2} = \dfrac{ \cancel{2} × Radius}{ \cancel{2}} }[/tex]

We get that ,

[tex] \qquad \: \rm {Radius = \dfrac{Diameter}{2} }[/tex]

Therefore , we can say that radius of circle is half of its diameter .

Now using this firstly we are finding radius of circle . So :

[tex] \longmapsto \quad \: \boxed{\rm{ Radius = \frac{7}{2} \: \: inches}}[/tex]

Now , we are moving towards our final solution .

So ,

[tex] \longrightarrow \quad \: Area_ { (Circle)} = \pi( \dfrac{7}{2} ) {}^{2} [/tex]

Calculating further :

[tex]\longrightarrow \quad \: Area_ { (Circle)} = \pi \times \dfrac{7}{2} \times \dfrac{7}{2} [/tex]

After multiplication of 7/2 with 7/2 we get :

[tex]\longrightarrow \quad \: Area_ { (Circle)} = \pi \times \dfrac{49}{4} [/tex]

On dividing 49 by 4 we get :

[tex]\longrightarrow \quad \: \blue{{\boxed{\frak{Area_ { (Circle)} = 12.25\pi \: inches {}^{2} }}}}[/tex]

Remember one thing , we haven't put value of π as 22/7 or 3.14 because in the question it is given that we have to find the area of circle in terms of pi .

Answer:

13 dollars a pizza because if you put 4x13 that is 52 then add the wings 8$ that is your answer 60....

Step-by-step explanation:

Hopefully It helped ya... (:

Answer:

p = 12

Step-by-step explanation:

Given:

Jalen bought 4 pizzas. He also spent $8 on wings. He paid a total of $60. He can use the equation 4p + 8 = 56 to determine the price of each pizza.

To Find:

How much was each pizza?

Solution:
Since it already given a equation thus we can just solve using the equation given:

4p + 8 = 56

Subtract 8 from both sides

4p + 8 = 56

      - 8     -8

-----------------------

4p = 48

Divide both sides by 4

4p/4 = 48/4

p = 12

Hence, each pizza cost $12.

The question is an illustration of sample and population, and the estimate of the population of squirrel in the park is 55

The given parameters are:

Marked squirrels = 43

Captured squirrels = 50

Of the 50 captured squirrels, 38 are from the marked squirrels.

This means that the number of unmarked squirrels is:

Unmarked = 50 - 38

Evaluate

Unmarked = 12

The population of the squirrel is then calculated using:

Population = Marked + Unmarked

So, we have:

Population = 43 + 12

Evaluate the sum

Population = 55

Hence, the estimate of the population of squirrel in the park is 55

The vertices of the polygon form a trapezoid, and the area of the polygon is 28 unit squares

The vertices are given as:

C = (3,3)

A = (8,-2)

S = (3,-4)

H = (0, -2)

The area of the polygon is calculated using:

[tex]A = \frac 12 \sum\limits^{n-1}_{k = 0}(x_ky_{k+1} - y_kx_{k+1})[/tex]

So, we have:

A = 1/2 * |(3 * -2 - 8 * 3 + 8 * -4 - 3 * -2 + 3 * -2  - 0 * -4 + 0 * 3 -3 * -2)|

Evaluate

A = 1/2 * |-56|

Remove the absolute bracket

A = 1/2 * 56

Evaluate the product

A= 28

Hence, the area of the polygon is 28 unit square

Answer:

number of action figures = 3 + 6(n-1)

at n = 9: number of action figures = 51

Step-by-step explanation:

first row: 3

second row: 6 more than the row before it (3) = 6 + 3 = 9

third row: 6 + 9 = 15

arithmetic series: [tex]a_n = a_1 + (n-1)d[/tex], where

[tex]a_n[/tex] is the nth term in the output

[tex]a_1[/tex] is the first output

n is the input

d is the difference between terms

here, we are given the row, and we want to figure out the number of action figures. thus, row = input and number of action figures = output.

the first output, in the first row, is 3

the difference between the number of action figures in each row is 6

thus, our formula is

[tex]a_n = 3 + (n-1)6 = 3 + 6(n-1)[/tex]

when the row is 9, the number of action figures is equal to

3 + 6(9-1) = 3 + 6 * 8 = 51

Answer: The answer is five

Step-by-step explanation:

Set y = z

50x + 75 = 65x

Subtract 50x from both sides

50x (-50x) + 75 = 65x (-50x)

75 = 15x

Divide both sides by 15

75 (/15) = 15x (/15)
