Question

Find the area of a circle with a radius of 6.7 m to the nearest square unit

Answer 1

A = 141 m²

Explanation:

The formula of an area of a circle with radius r:

`A_O=\pi r^2`

We have r = 6.7m. Substitute:

`A_O=\pi\cdot6.7^2=\pi\cdot44.89\approx3.14\cdot44.89=140.9546\approx141\ m^2`

Answer 2

141 Square units.

Explanation:

Area of a circle is equal to pi*radius squared.

`A = \pi * 6.7^(2) \\A = 141.026....\\A \approx 141 u^2`
