Answer:

30,631 inches
2553 feet

Step-by-step explanation:

The length of one revolution of the sprocket is ...

C = 2πr = 2π(1.5 in) = 3π in

Then the length of 3250 revolutions is ...

3250(3π in) = 30,630.53 in

About 30,631 inches of chain travel past the sprocket in one minute.

There are 12 inches in a foot, so the number of feet is ...

30,630.53 in/(12 in/ft) = 2552.54 ft

About 2553 feet of chain travel past in one minute.
