Answer:

A = 200.96 units^2

Step-by-step explanation:

We know the circumference is given by

C = 2 * pi *r

Approximating pi by 3.14

50.24 = 2 * 3.14 *r

50.24 = 6.28 r

Divide each side by 6.28

50.24/ 6.28 = 6.28r/6.28

8 =r

Now we can find the area

A = pi * r^2

A = 3.14 * r^2

A = 3.14 (8)^2

A = 200.96 units^2
