Answer:

C.) [tex]7,854[/tex] [tex]cm^2[/tex]

Step-by-step explanation:

use the area of a circle formula:

[tex]A=\pi r^2[/tex]

Insert the radius:

[tex]A=\pi *50^2[/tex]

Simplify exponents:

[tex]A=\pi *2500[/tex]

Simplify pi:

[tex]A=3.14*2500\\A=7850[/tex]

Option C is the closest to 7850.

Finito.
