Question

A circle has a radius of 8cm. What is the AREA? Use this formula - A = pi X radius squared.

Answer 1

Explanation:

The formula for the area of a circle:
`A=\pi r^(2)`

Given:

• Radius = 8 cm

Substitute 8 for r (radius):

`A=\pi 8^(2)`

Solve:

`A=\pi (64)`

`A=64\pi`
`or`
`201.062 cm^(2)`
`rounded.`
