Question

The circumfrence of a circle is $264cm$. Find its area.

Answer 1

We have,

Circle $=264$

radius of circle $=r$

Circumference $=2\pi r$ $2\pi r=264$

$\frac{22}{7}\times r=132$

$r=132\times \frac{7}{22}$

$r=42cm$

Area $=\pi r^2$

$=\frac{22}{7}\times 42\times 42$

$=5544c{m}^2$

Hence, this is the answer.
