Question

The Cole family owns an above-ground circular swimming pool that has walls made of aluminum. ​ ​Find the length (l) of aluminum surrounding the pool as shown if the radius is 15 feet. ​(use π=3.14 )

Answer 1

The length of aluminium surrounding the pool is 94.20 ft.

Explanation:

The picture represents the circular swimming pool that has walls of aluminium surround it.

The circumference of a circle is the distance around a circle. It is the curved line that goes round the circle. The question wants us to find the circumference of the aluminium surrounding the circular pool.

circumference of a circle = 2πr

circumference of a circle = 2 × 3.14 × 15

circumference of a circle = 30 × 3.14

circumference of a circle = 94.2 ft

The length of aluminium surrounding the pool is 94.20 ft.
