Question

The radius of a circle is 4 centimeters. What is the area?

r=4 cm
Give the exact answer in simplest form.

Answer 1

50.24

Explanation:

The question is asking us to find the area when the radius is 4.

First, remember the formula of finding the area:

`A = \pi r^2`

The radius is 4 so we plug it in;

A = π(4)^2

A = π(16)

A = 50.24

Answer 2

50.24

Explanation:

Area of a circle= πr^2

Where we will take radius as 4cm and pi as 3.14 approx

= 3.14 x 4 x 4

= 3.14 x 16

= 50.24

So the area is 50.24 cm^2
