The diameter of a circle is 0.82 inches. What is the approximate area of the circle?
Diameter = 2 x radius
Area of circle formula: πr²
0.82/2 gives us the radius.
The radius is 0.41 so let's square that.
0.41²= 0.1681
Your answer is 0.1681π OR approximately 0.527834*
(*since 0.1681 times 3.14 is approximately 0.527834)
Answer:
0.527834
Step-by-step explanation:
Diameter = 2 x radius
Area of circle formula: πr²
0.82/2 gives us the radius.
The radius is 0.41 so let's square that.
0.41²= 0.1681
0.527834

Here is trapezoid A in the coordinate plane:
If you drew Trapezoid C, the image of A after a reflection over the y-axis, what would be the coordinates of each of the vertices?
Answer:
(-2,1) (-2,3) (-4,1) (-4,4)
Step-by-step explanation:
Simply select each of the points, Count how many squares away that point is away from the line of reflection (the y-axis) and Put that point the same distance/amount of squares away on the other side of the y-axis. Join up the points and then you get your answer!
What is 4 log Subscript one-half Baseline w + (2 log Subscript one-half Baseline u minus 3 log Subscript one-half Baseline v) written as a single logarithm? 4 log Subscript one-half Baseline 2 Superscript 4 Baseline u squared minus v cubed
The correct answer is B).
The single solution is [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex].
What is logarithmic?The exponent to which the base of the logarithm should be raised in order to obtain the number N is the logarithm of any number N, if interpreted as an exponential form. Numerous astronomical and scientific calculations involving large numbers can benefit from its use. As an inverse of the exponential function, logarithmic functions are closely related to exponential functions.
Given Equation
[tex]4log_\frac{1}{2} w + (2log_\frac{1}{2} u - 3log_\frac{1}{2} v)[/tex]
[tex]mlog_an = log_an^{m}[/tex]
equation is
[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} u^2 - log_\frac{1}{2} v^3)[/tex]
and [tex]log_an - log_am = log_a\frac{n}{m}[/tex]
and [tex]log_an + log_am = log_amn[/tex]
[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} \frac{u^2}{v^3} )[/tex]
and [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex]
Hence the equation is [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex].

I WILL MARK AS BRAINLIEST! Write and equation that represents the points on the table
Step-by-step explanation:
y = ax +b
2 = 0a+ b => b = 2
4 = -2a + b
4 = -2a +2
2a = 2-4
2a = -2
a = -1
so, y = -x + 2

find three consecutive integers for which 3 times the sum of the first and third integers is -342? show step by step
Answer:
The integers are -58, -57, -56.
Step-by-step explanation:
The difference between two consecutive integers is 1.
If you let the smallest of the three consecutive integers equal x, then the next greater one is x + 1, and the greatest of the three is x + 2.
Integers: x, x + 1, x + 2
The sum of the first and third is: x + x + 2
3 times the sum of the first and third is: 3(x + x + 2)
That product equals -342.
3(x + x + 2) = -342
3(2x + 2) = -342
Divide both sides by 3.
2x + 2 = -114
Subtract 2 from both sides.
2x = -116
Divide both sides by 2.
x = -58
x + 1 = -57
x + 2 = -56
The integers are -58, -57, -56.

Circle question of the rug
That you needed answer for is ;
3/4 pi^2
Step-by-step explanation:
Proof 1/4 pi r^2
We can state the radius of small rug is 3ft
to show Area pi 3^2 = pi 9
If the large rug is 3x this size
then pi 9^2 = pi81
So the ratio here is 1 : 9 when 3 cm or 1 : 3 radius
Ratio is 1 : 9 when 1cm or 1 : 3 radius
When 1 : 9 cm when 5cm or 1 : 3 radius
So if we are considering an expression of the larger rug
that shows 3: 1 more radius to that of the small.
1/4 pi^2 becomes 3/4 pi^2 of the smaller rug
As this is 3 x 1/4 pi^2 we show 3/4pi r^2

On the graph, △DEF was transformed to create △DGH.
Which transformations show that △DEF is similar to △DGH?
A
a dilation by a scale factor of 6 and then a 180° rotation about the origin
B
a dilation by a scale factor of 6 and then a translation 6 units down and 6 units left
C
a dilation by a scale factor of 3 and then a 180° rotation about the origin
D
a dilation by a scale factor of 3 and then a translation 6 units down and 6 units left
Answer:
it's B
Step-by-step explanation:
by analyzing it I figured it was 100% B
Answer:
C. a dilation by a scale factor of 3 and then a 180 degrees rotation about the origin.
Step-by-step explanation:
G is the same point transformed as E and H is the same as point F.
Since G is now (-9,0) that was multiplied 3 times from (3,0) before it was rotated. Which would show that the answer is probably C or D.
Next, the answer looks as though it has been rotated around D or the origin by 180 degrees but we don't know that quite yet.
So check if you dilated triangle DEF by a factor of 3 then translated it down 6 units point E would now be (9,-6).
Then translate it to the left 6 units. (3, -6). That's not the same as triangle DGH.
So the answer is C.
Hope this helps! If it does brainliest would be appreciated.
