Question

A circular garden has a circular fountain in the center. The outer edge of the fountain is 7.5 feet from the outer edge of the garden. The diameter of the fountain is 5 feet. What is the circumference of the garden?

Answer 1

The circumference of the garden is 62.84 ft

Explanation:

Given;

diameter of the fountain, d = 5 feet

radius of the fountain, r = d / 2 = 2.5 feet

distance between the outer edge of the fountain and the garden = 7.5 feet

The radius of the garden = radius of the fountain + outer edge distance

The radius of the garden = 2.5 feet + 7.5 feet = 10 feet

The circumference of the garden = 2πr

The circumference of the garden = 2 x π x 10

The circumference of the garden = 62.84 ft

Therefore, the circumference of the garden is 62.84 ft
