A barrel shaped like a cylinder is laid on its side and rolled up a ramp. The barrel has a circular base that is
0.9m
in diameter. If the barrel turns
37
times in being rolled up the ramp, how long is the ramp?
Use the value
3.14
for
π
. Round your answer to the nearest tenth. Do not round any intermediate steps.
