Question

A children's pony ride at a zoo has ponies attached to a carousel pole in the center of a circle that the ponies walk around as children ride. Suppose the diameter of the circle i 25 feet. How many feet does a pony walk to complete one trip around the circle?

Answer 1

We simply need to solve for the circumference of the imaginary circle.

Given:
Diameter = 25 feet.

Circumference = 2 * radius * π OR Circumference = diameter * π

C = 25feet * 3.14
C = 78.50 feet

The pony will walk 78.50 feet to complete one trip around the circle.
