Answer 2

Answer:

Area is 1256.637 sq inches

Step-by-step explanation:

Given that

Radius of circle is 20inches

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

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