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)

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
