Question
Winch A winch of radius 2 $\mathrm{ft}$ is used to lift heavy loads. If the winch makes 8 revolutions every 15 $\mathrm{s}$ , find the speed at which the load is rising.
Step 1
The circumference of a circle is given by the formula $C = 2\pi r$, where $r$ is the radius of the circle. In this case, the radius of the winch is 2 ft, so the circumference is $C = 2\pi(2) = 4\pi$ ft. Show more…
