Ricky is building a brick path around the fountain in his backyard. The diameter of the fountain is 7 ft. How long must the path around the fountain be? (Use 3.14 for pi)

The path length is just the circumference of a circle with a radius of 7/2 = 3.5ft

So.....the path lebgth =

2 pi * radius =

2 * 3.14 * 3.5 = 21.98 ft

Since the brick path is around the fountain, which is circular and has a diameter of 7 (radius: 3.5), we can find the circumference of the circle.

Circumference: pi * 2 * r

= pi * 2 * 3.5

= 7 pi

= 7 * 3.14

= 21.98

Answer:

21.98 ft
