A dog is leashed to a point in the center of a large yard, so the path the dog is able to explore is circular. The leash is 20 feet long. What is the length of the path? Round to nearest tenth.
+934 If the path is the circumference of the circle, the leash is the radius of 20 feet and the circumference is 2 * radius * pi. The length of the path is 20 * 2 * pi= 40pi= 125.7.
