How many times a wheel of radius 28 cm must rotate to go 352 m?
It is given in the question that,
Total distance to be covered by wheel = 352 m
Radius of wheel = 28 cm
Circumference of the circle = 2
r
= 2 × 
× 28
= 2 × 22 × 4
= 176 cm
Hence,
Number of rotations = 
= 200
∴ The wheel will rotate 200 times
