1.	a cyclist goes around a circular track once every two minutes if the radius of the circular track is 105 metres calculator his speed.
Answer» GIVEN :-Radius , r = 105time t = 2min= 120 secondwe know alsocircumference or DISTANCE of CIRCLE = 2πr⇒2×22/7×105⇒ 660 m∴ SPEED = distance / time⇒660 m/ 120⇒5·5m/s
