Question

A car makes 50,000 revolutions to travel a distance of 121 km. What is the diameter of the wheel of car?​

Answer 1

Answer:

no. of revolutions taken = 50,000

distance travelled = 121 km

distance travelled in one revolution(circumference of wheel) = 12100000/50000 cm

2πr = 242 cm

2 X 22/7 X r = 242

44/7 X r = 242

r = 242 X 7/44

r = 77/2

diameter of wheel(in cm) = 77/2 X 2

                                          = 77 cm
