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.
