Answer:
L = 94.2 ft
n ≈ 5
Step-by-step explanation:
d = 500 ft
R = 15 ft
The pony walks in one ride around the circle:
L = 2*π*R = 2*3.14*15 ft = 30*π ft = 94.2 ft (One ride around the circle).
In order to determine how many times (n) can the pony give a ride before it needs a drink, we can apply
n = d / L = 500 ft / 94.2 ft = 5.308 ≈ 5
