Question

A circular gear turns 60 per hour. through how many radians does it turn in a 24-hour day?

Answer 1

For 1 turn it passes through 2 pi radians

So number of radians it turns through in 24 hours = 60 * 24 * 2 pi = 9047.8 radians to nearest tenth.

Answer 2

Answer: 8pi rad/day

Explanation:

60 degrees*24 hours= 1440 degrees

1440 degrees/ rad= 8pi rad/day
