Question

Ruby is visiting a wildlife center to gather information for her term paper. The center has a circular pond with a diameter of 20 meters. What is the approximate area of the pond?

A. 1,256 square meters

B. 628 square meters

C. 314 square meters

D. 62.8 square meters

Answer 1

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

Answer 2

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.
