Question

Find the area of the circle whose circumference is:
$88cm$

Answer 1

As we know that,

Circumference of circle $=2\pi r=88cm\left(\text{Given}\right)$

$\Rightarrow r=\frac{88\times 7}{22\times 2}=2\times 7=14cm$

Thererfore,

Area of circle $=\pi r^2=\frac{22}{7}\times 14\times 14=616{cm}^2$
