Question 605878
If "A circular gear turns 60 degrees per hour" and it turns 24 hours, then it will turn a total of 60*24 = 1440 degrees.


Notice that 1440/360 = 4. So this means it will complete 4 full revolutions in 24 hours.


We know that one full revolution in radians is {{{2pi}}} radians. So 4 full revolutions is {{{4*2pi=8pi}}} radians.
