Verified Answer :

The rule to figuring out the area of a circle is A=r^2*pi. 

So since the radius is half of the diameter you will ne to cut 25 in half. Which equals 12.5. OK so now we need to multiply 12.5 by 12.5 which equals 156.25.

So i believe that the Answer is C. 156.25pi m^2

Leader

Diameter = radius 2
25 = radius 2
radius = 12.5

Area = radius^2 pi
Area = 12.5^2 pi

Area = 156.25 pi m^2

Your answer is C.
