Question

a cyclist is moving in a circular track of radius 230m. Caluculate his speed if he takes 11s to complete a round​

Answer 1

Answer:

Explanation:

Radius of circle = 230m

Circumference of circle = 2πr

                                       = 2 x 3.14 x 230

                                       = 1444.4 m

Time taken to travel 1 round = 11s

Distance = 1444.4 m

Speed = Distance/Time

           = 1444.4m/11s                                                  

           = 131.30 m/s
