Question

A boy complete one circular round in 8 sec, if radius of circle is 6m then calculate speed of boyFff​

Answer 1

Answer:

Time = 8 sec and radius is 6m

Now The Circumference = 37.68 m (Take pi = 3.14)

Thus the speed = Tot. Distance / Tot. Time  

=> Speed = 37.68/8  = 4.71 m/s

Thus speed is 4.71 meter per second
