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.

Step-by-step explanation:

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

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

Thus, the area of the pond,

[tex]A=\pi\times (10)^2[/tex]

[tex]=\frac{22}{7} \times 100[/tex]

[tex]=\frac{2200}{7}=314.285714286\approx 314\text{ square meter}[/tex]

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