Question

A cyclist goes around a circular track once every 2 minutes . If the radius of the circular track is 105 metres , calculate his speed(π = 22/7)​

Answer 1

Answer:

5.5 m

Explanation:

If the radius of the circular track is 105 metre, calculate his speed. (Given pi= (22)/(7)) Thus, the speed of cyclist on the circular track is 5.5 metres per second.

Answer 2

Answer:

Explanation:

The circumference of the circle=2π x Radius = 2*22/7*105= 660 meter

We know Speed= distance/time

So speed=660m/(2*60)sec = 11/2 m/s = 5.5 m/sec
