+142 Daphne has a rope that is 60 meters long. She wants to use it to mark the boundary of a circle whose radius is an integer. What's the largest possible radius for her circle, in meters?

Boundary is another way of saying circumference.
Circumference = pi times diameter
60 = 3.14 x D
D = 60/3.14 = 19.11
Radius is half the diameter so the radius would be 9.55
Truncating to an integer, the largest radius would be 9 meters
