Mathematics

Answer:

   7850 m^2

Step-by-step explanation:

The circumference of a circle is given by

C = 2*pi *r

314 = 2 * 3.14 *r

314 = 6.28 r

Divide each side by 6.28

314/6.28 = 6.28 r/6.28

50  m= r

Now we need to find the area

A = pi * r^2

A = 3.14 *r^2

A = 3.14 (50)^2

  = 3.14 (2500)

   7850 m^2
