Question

You are laying brick for a custom circular patio fire pit. The radius of the fire pit is 36 inches. In square feet, what

amount of patio space is needed for the fire pit?
O 9.42 square feet
O 28.26 square feet
O 113.04 square feet
226.08 square feet
4,069.44 square feet

Answer 1

The answer is 28.26 square feet.

Explanation:

The area of a circle is
`\pi r^(2)`, so if the radius is 36,
`\pi *36^(2)` is equal to about 4071.5. The formula for converting square inches to square feet is to divide by 144, and
`(4071.5)/(144)` is around 28.26.
