Question

Calculate the area of a circle whose radius is 7cm

Answer 1

The area of a circle is given by the following formula

`A=\pi r^2`

Where r represents the radius of the circle.

Since the given circle has a radius equal to 7cm, the area is

`A=\pi(7)^2=49\pi=153.938040026\ldots`

The area of this circle is 49π cm².
