QUESTION:

Area of circle is 221.76 sqrt. cm. find its circumference.

ANSWER:

We used the formula here;

area of circle =

$\red{\pi \times {radius}^{2} }$

Circumference of circle =

$\green{2 \times \pi \times radius}$

now come to main question;

area of circle = 221.76 sqrt cm

$\pi \times {r}^{2} = 221.76 {cm}^{2} \\ \frac{22}{7} \times {r}^{2} = 221.76 {cm}^{2} \\ {r}^{2} = 221.76 \times \frac{7}{22} \\ {r}^{2} = 70.56 \\ r = \sqrt[2]{70.56} \\ r = 8.4cm$

$\huge\pink{radius = 8.4cm}$

Circumference of circle =

$2 \times \frac{22}{7} \times 8.4cm \\ 52.8cm$

$\huge\red{circumferene = 52.8cm}$
