Question

A circular pool has a diameter of 25 feet. A 2-foot-wide sidewalk borders the entire pool. What is the approximate circumference of the outside edge of the sidewalk?

Answer 1

84.834 in

Explanation:

Given data

Diameter of pool= 25 ft

Width of side walk= 2ft

Hence the diameter of the pool and the sidewalk combined= 25+2= 27ft

The radius of the pool and the sidewalk combined= 27/2= 13.5ft

Circumference= 2πr

Circumference= 2*3.142*13.5

Circumference= 84.834 in

Hence the circumference is 84.834 in
