If the circumference of a circle is 528 cm, then its area is ______ c m 2 . ( π = 22 7 ) Options: A . &nbsp 22176 B . &nbsp 22576 C . &nbsp 23176 D . &nbsp 24576

Answer: Option A : A Circumference of the circle = 2 π r = 528 c m (where r is the radius of the circle) ⇒ r = 528 2 π = 84 c m Now, area of the circle = π r 2 = 22 7 x 84 2 = 22176 c m 2

If the circumference of a circle is 528 cm, then its area is _____

Question

If the circumference of a circle is 528 cm, then its area is ______ $c m^{2}$ .
$(π = \frac{22}{7})$

Options:

A . 22176

B . 22576

C . 23176

D . 24576

Answer: Option A
:
A

Circumference of the circle
$= 2 π r = 528 c m$
(where r is the radius of the circle)

$\Rightarrow r = \frac{528}{2 π} = 84 c m$

Now, area of the circle = $π r^{2}$

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