c, since the radius is 10 multiply by 2 and 100 x 3.14 is 314

Answer: The approximate area of the given circular pond is 314 square meter.

Explanation:

Since, the diameter of the circular pond = 20 meter,

⇒ Radius of the pond = 20/2 = 10 meter.

Thus, the area of the pond,


A=\pi* (10)^2


=(22)/(7) * 100


=(2200)/(7)=314.285714286\approx 314\text{ square meter}

Hence, The approximate area of the given circular pond is 314 square meter.
