Class 7MathematicsPerimeter and Area

How many times a wheel of radius 28 cm must rotate to cover a distance of 352 m? (Take π =22/7)

Verified Answer

Radius of the wheel = 28 cm

Circumference = 2πr = 2 ×22/7× 28 = 176 cm

Distance to be covered = 352 m or 352 × 100 = 35200 m

Number of rotation made by the wheel to cover the given distance=35200/176

Hence, the required number of rotations = 200.
