Question

A metal pole connects a horse's 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 house walks, a circle begins to form on the ground. If the rod is 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 is given by the formula C = 2πr, where r is the radius of the circle. In this case, the radius of the circle is equal to the length of the metal pole, which is 2.5 yards.

Substitute r = 2.5 yards into the formula:
C = 2 * 3.14 * 2.5
C = 15.7 yards

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

Answer: 15.7 yards
