Question

The radius of a circle is 10 m. Find its area to the nearest whole number.

Answer 1

given:

radius= 10 m

to find:

the area of the given circle.

solution:

$a = \pi {r}^{2}$

$a = \pi \times {10}^{2}$

$a = 314.15927 \: {m}^{2}$

$a = 314 \: {m}^{2}$

therefore, the area of the given circle is 314 square meters.
