a boat that is pulling a water skier drives in a circle that has a radius of 80 feet. The skier is moving outside the path of the boat in a circle that has a radius of 110 feet. Find the distance traveled by the boat when it has completed a full circle. How much further has the skier traveled?
---------------
Formula: Circumference = 2(pi)r
Boat distance = 2(pi)80' = 260pi ft
--------------------
Skier distance = 2(pi)(80+110) = 2(pi)190 = 380(pi) ft.
---------
How much further did the skier travel?
380(pi)-260(pi)= 120(pi) ft.
