**
In one revolution of the drum the hoist will raise up equal to the circumference of the drum.
Circumference of drum=2πr=2π10/2=2π5=10π inches
Hoist must be raised 3 ft = 36 inches
Number of revolutions the drum must turn=36/10π
Each revolution drum turns 360º
Drum will rotate 360*36/10π=412.5º
ans:
The number of degrees thru which the drum must rotate to raise the hoist 3 ft=412.5º
