Question

A cyclist moving on a circular track of diameter 210 meter in 1 min calculate the speed

Answer 1

radius = 201/2 = 105 m
circumference = 2πr = 2×(22/7)×105 = 660 m

time = 1 min = 60 sec
speed = distance/time = 660/60 = 11 m/s

Answer 2

Answer:

Explanation:

Given :-

Diameter = 210 m

Radius = 201/2 = 105 m

Time taken = 1 min = 60 sec

To Find :-

The Speed

Formula to be used :-

Circumference of Circle = 2πr

Speed = Distance/Time

Solution :-

Circumference of Circle = 2πr

Circumference of Circle = 2×(22/7)×105

Circumference of Circle = 660 m

Speed = Distance/Time

Speed = 660/60

Speed = 11 m/s

Hence, the speed is 11 m/s.
