Question

2. A circular patio has a diameter of 18 feet. How

many square feet of tile will it take to cover the
patio?

Answer 1

Answer: So to cover the patio it would take 255 whole tiles. 254.469 if you want to be exact.

Explanation:

When finding flooring needed we are finding for area. We know the formula for finding the area of a circle is A=
`\pi r^(2)` so we plug in our known variables...

we know r because radius is half of diameter and diameter was given in problem. So half of 18 is 9.

r=9

A=
`\pi 9^(2)`

A=
`\pi`81

A=254.469
