Answer 1

@Ahsome

Answer 2

What is the equation for the area of a circle?

Answer 3

pi r^2

Answer 4

if the equation for the area as you stated is pi r ^2. then, substitute the value of the radius: 10. therefore (pi 10 ^ 2)^2

Answer 5

hope i helped!

Answer 6

C?

Answer 7

yes.

Answer 8

awesome! thx!!

Answer 9

\[\Huge{Area=\pi\times r^2}\]\[\Huge{Area=\pi\times 10^2}\]\[\Huge{Area=\pi\times 100}\]\[\Huge{Area=100\pi \text{ }m^2}\]Therefore, its C
