Question

The diameter of a wheel is 28 cm. How many revolutions will it make on covering 176​

Answer 1

Answer:

Diameter of a wheel=28cm

Radius of a wheel=228=14cm

Distance travelled to make one revolution=Circumference of the wheel=2πr

2π×r=2×722×14=88cm

To make one revolution the wheel has to travel=88cm

Number of revolutions to travel 352m is =DistancetravelledtomakeonerevolutionTotaldistancetravelled=88352=4

Answer 2

Answer:

2 revolution

Step-by-step explanation:

Circumference = 88cm

No of revolution = Distance/ Circumference

176/88 = 2
