Question

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

Answer 1

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

Step-by-step 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
