Answer 2

Given -

The radius of a circle is 42 m

To find -

The area of circle

Solution -

As we know that,

Area of circle = $\pi {r}^{2}$

Where,

r is the radius of circle.

Put the value of r we get

Area of circle = $\pi \times {42}^{2}$

Square means multiply the given values with itself twice.

Square of 42

$42 \times 42 = 1764$

Area of circle = $\pi \times 1764$

The value of π is 3.14.

Area of circle = $3.14 \times 1764$

Area of circle = $5538.96$

Hence,

Area of circle is 5538.96 ${m}^{2}$
