A tetherball is attached to the end of a 3-meter rope. The rope is attached to a pole thatis 5 cm in diameter. Estimate the greatest number of timees the rope could rap around the pole. Use 3 for pi(3.14) to make your estimate.

Answer 1

If I have to use 3 for pi, each full loop around the pole requires pi D = 15 cm. The rope will then go around about
N = 30 m/0.15 m = 20 times

Actually if you consider that pi = 3.142.. and the rope may wrap over itself, a more likely number is 18 or 19 turns

Answer 2

20
