A circle has a radius of 28 feet. A larger circle goes around the smaller circle that is 4 feet wide.

About how many feet of fencing are needed to go around the pool path? Use 3.14 for Pi.
88 ft
100 ft
176 ft
201 ft

Respuesta :

The number of feet of fencing that is needed to go around the pool path is D. 201 ft.

How to calculate the number of feet?

We have a pool with a radius of 28 feet. The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.

= (28 + 4) feet

= 32 feet

The circumference of the outer edge of the pool path would be equal to the perimeter.

p = 2 * pi * r

p = 2 * 3.14 * 32

p = 200.96 feet

p = 201 feet
