Answer:

Area is 1256.637 sq cm

Step-by-step explanation:

Given that

Radius of circle is 20cm

To find

Area of circle

Solution

As we know that

$area \: of \: circle = \pi \times {radius}^{2}$

hence

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

we get

$area \: of \: circle = \frac{22}{7} \times {20}^{2}$

by multiplication we get

$area \: of \: circle = 1256.637 {cm}^{2}$
