Question

If the circumference of a circle is 528 cm, then its area is ______ $c{m}^2$.

$(\pi =\frac{22}{7})$

• A. 22176
• B. 22576
• C. 23176
• D. 24576

Answer 1

The correct option is A

22176

Circumference of the circle
$=2\pi r=528cm$
(where r is the radius of the circle)

$\Rightarrow r=\frac{528}{2\pi }=84cm$

Now, area of the circle = $\pi r^2$

= $\frac{22}{7}$ x ${84}^2$ = 22176 $c{m}^2$
