Question

A circular water fountain in the town square has a 112-foot circumference. How far is the center of the fountain from the outer edge? Round to the nearest whole number.

Answer 1

18 feet

Explanation:

The distance of the center of the fountain from the enter edge is equal to the radius of the circular fountain.

Use the circumference formula, c = 2
`\pi`r, to find the radius.

c = 2
`\pi`r

112 = 2
`\pi`r

18 = r

So, to the nearest whole number, the distance between the center of the fountain and outer edge is 18 feet.
