Question

Find the area of the circle whose circumference is:
$62.8cm$

Answer 1

As we know that,

Circumference of circle $=2\pi r=62.8cm\left(\text{Given}\right)$

$\Rightarrow r=\frac{62.8}{2\times 3.14}=\frac{62.8}{6.28}=10cm$

Therefore,

Area of circle $=\pi r^2=3.14\times 10\times 10=314{cm}^2$
