Question

A circle has a radius 6 inches. If a sector of the circle has an area of 10.8Tt square inches, then what
percent of the circle's area does the sector represent?

Answer 1

The area of a circle is A = pi • r • r

A = pi • 6 • 6

A = 113.097335529 square inches

To get the percent of the section, divide the section by the whole, and multiply by 100.

10.8/113.097335529 = 9.54929658553%
