Answer:

B) A = 25π

Step-by-step explanation:

The area of a circle is calculated with the formula \pi * r^2

The radius is half of the diameter, which in this case is 10.

Plugging it in, you get 5^2\pi

5^2 = 25\\

A = 25\pi

The formula for the volume of w sphere is v=4\3 r3 what is the formula solved for r?
Lyrx [107]
V of w sphere = \frac{4}{3}\pir³
Multiply by 3 on either sides to get rid of the fraction.
V * 3 =  \frac{4}{3} *3 \pi r^3
3V = 4\pir³
Now divide either sides by 4\pi to isolate r³
\frac{3V}{4 \pi } =  \frac{4 \pi }{4 \pi }r³
4\pi and 4\pi cancels out
\frac{3V}{4 \pi } = r³
Take the cube root to isolate r.
\sqrt[3]{ \frac{3V}{4 \pi } } =  \sqrt[3]{r^3}
the cube root cancels the cube

\sqrt[3]{ \frac{3V}{4 \pi } } = r
