Question

A dog is tied to a stake in the ground and runs around in a circular pattern. His running section is a circle with a diameter of 15 feet. In terms of pi, what is the area of the section that the dog runs?

Answer 1

56.25π ft²

Step-by-step explanation: this is the correct answer

Answer 2

56.25π ft²

Explanation:

a = πr²

d = 15 ft

r = 15 ft/2 = 7.5 ft

a = π × (7.5 ft)²

a = 56.25π ft²
