Question

A cyclist goes around a circular track once every 2 min. If the radius of the circular track is 110 cm , calculate the speed of cyclist.

Answer 1

Hy friend ------

given :-
Radius , r = 110

time t = 2min
= 120 second

we know also

circumference or distance of circle = 2πr
⇒2×22/7×110
⇒ 691.43m

∴ speed = distance / time

⇒691.43 m/ 120

⇒5·76m/s
