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
