Question

If a point on the rim of a 21cm diameter fly wheel travels 5040 m in a minute through how many radians does the wheel turn in a second

Answer 1

Answer:

circumference

=>  2 x 3.141 x 10.5= 65.982cm = 0.65982m

Step-by-step explanation:

5040m per minute.

1 second = 5040/60=  84 m

84m/0.65982= 127.31 revoloutions

127.31x 2pi = 254.61pi radians
