Answer 1

Area = pie x radius squared
50 squared = 2500
2500 x pie = 7853.9
Therefore the answer is c

Answer 2

Answer:

C.) $7,854$ $cm^2$

Step-by-step explanation:

use the area of a circle formula:

$A=\pi r^2$

Insert the radius:

$A=\pi *50^2$

Simplify exponents:

$A=\pi *2500$

Simplify pi:

$A=3.14*2500\\A=7850$

Option C is the closest to 7850.

Finito.
