Question

5. How many times a wheel of radius 28 cm must rotate to cover a distance of 352 m?​

Answer 1

Answer:

It is given that the radius is 28cm

circumference is 2πr =2×22/7×28= 2×110 =220cm To go286m² It will be 286×100=2860000/22=13000

Answer 2

Circumference of wheel=176cm
Distance=35200 cm
Rotation=35200/176
=200 times
