1.	A wheel of a cart is making 4 revolutions per second. If the diameter be 84 cm, find the speed of the wheel in cm/s.
Answer» Diameter of the wheel is 84 cmso circumference of the wheel=π×diameter=22/7×84cm=22×12cm=264cmdistance covered in one revolution=circumference of the wheel.In 1 sec there are 4 revolutionsso distance covered in 1sec=4×264cm=1056cmso speed of the wheel is 1056cm/sec
