Question

A circular fountain has a radius of 9.4 feet. Find its diameter and circumference to the nearest tenth.

Please Help.

Answer 1

diameter = 18.8 ft

circumference = 56.1 ft

Explanation:

diameter = 2 x radius = 2 x 9.4 = 18.8 ft

circumference = 2
`\pi`r = 2
`\pi`(9.4) = 56.061 rounded to the nearest tenth is 56.1
