Question

A circle has a diameter of 29 feet. What is the area? *

650.5 square feet
655.5 square feet
O 660.5 square feet
O 665.5 square feet

Answer 1

The answer is

660.5 square feet

Explanation:

Area of a circle = πr²

where r is the radius

From the question

diameter = 29 feet

To find the radius given the diameter we use the formula

`radius = (diameter)/(2) \\ radius = (29)/(2) \\ = 14.5 \: \: feet`

So the area of the circle is

`A = {14.5}^(2) \pi \\ = 210.25\pi \\ = 660.519...`

We have the final answer as

660.5 square feet
