Question

Kathy has a circular hot tub in her backyard with a

radius of 5.5 feet. She wants to place a decorative
border around the circumference of the hot tub. If the
border costs $6.70 per foot, how much will the border
for the hot tub cost? Type in your answer without the '$'
sign.

Answer 1

$231.42

Explanation:

Find the tub radius. It is C = 2πr, which here is C = 6.28(5.5 ft ) = 34.54 ft.

The border costs $6.70/ft. Multiply $6.70/ft by 34.54 ft:

($6.70/ft)(34.54 ft) = $231.42
