Hi there! Answer: r = 9 feet

We can find the area of a circle by using the following formula:

Area = pi × radius^2
A = pi × r^2
a = \pi {r}^{2}

In this particular question, we have the following data:

The area (A) is 254.34 square feet.
a = 254 . 34

Pi equals 3.14
\pi = 3.14

Now let's fill in the given formula.
254.34 = 3.14 \times r {}^{2}

Divide both sides by pi (in other words: divide by 3.14).
{r}^{2} = 81

Now take the square root of both sides of the equation. We only need to find the positive solution of this equation, because a radius cannot be negative.
r = \sqrt{81} = 9

Therefore, the radius is 9 feet.
~ Hope this helps you!

cos^2(x)+sin^2(x)=1 \\ 1=cos^2(4x)+sin^2(4x) \\  \\   cos(2x)=cos^2(x)-sin^2(x) \\ cos(8x)=cos(4 \times 2x)=cos^2(4x)-sin^2(4x) \\  \\   \\ 1+cos(8x)=cos^2(4x)+sin^2(4x) +cos^2(4x)-sin^2(4x) \\ cos^2(4x)+cos^2(4x)=2cos^2(4x)

Four rectangles are shown in the diagram. For which dilation is the ratio of the side lengths 2:3?
Sergio [31]

Answer:

the answer is the option C

C to B

Step-by-step explanation:

Let

x-----> the height of the rectangles

we know that

hA=8\ units

hB=6\ units

hC=4\ units

hD=2\ units

Find the ratios

rDC=\frac{hD}{hC}=\frac{2}{4}=\frac{1}{2}

rDB=\frac{hD}{hB}=\frac{2}{6}=\frac{1}{3}

rDA=\frac{hD}{hA}=\frac{2}{8}=\frac{1}{4}

rCB=\frac{hC}{hB}=\frac{4}{6}=\frac{2}{3}

rCA=\frac{hC}{hA}=\frac{4}{8}=\frac{1}{2}

rBA=\frac{hB}{hA}=\frac{6}{8}=\frac{3}{4}
