Question

A metal pole connects a horse saddle to another pole in the middle of the corral. This setup allows the horse to safely walk in circles around the pole in the center. As the horse walks, a circle begins to form on the ground. If the rod is approximately 2.5 yards long, what is the circumference of the circle on the ground? Use 3.14 for π>

Answer 1

The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle.

Since the metal pole is connecting the saddle to the center pole, the radius of the circle is equal to the length of the metal pole, which is 2.5 yards.

C = 2 * 3.14 * 2.5
C = 15.7 yards

Therefore, the circumference of the circle on the ground is 15.7 yards.
