A car is moving with the speed of 22 decimeter per second. If it performs 700 revolutions per second, the diameter of the wheel is? Share with your friends Share 3 Varun.Rawat answered this Let r be the radius of the wheel.Distance covered in 1 revolution = circumference of wheel = 2πr dmDistance covered in 700 revolutions = 700 × 2πr = 1400πr dmTime taken to perform 700 revolutions = 1 secSpeed = 22 dm/sec⇒1400πr1 = 22⇒1400 × 227×r = 22⇒r = 1200 dm⇒diameter = 2r = 2 × 1200 = 0.01 dm = 1 mm 4 View Full Answer
