Question

How many times a wheel of radius 14m must rotate to go 352m​

Answer 1

Answer:

Let us consider a wheel A of radius 28 cm. Let us assume the number of rotations required by wheel A to cover 352 m distance be n. Therefore, 200 total rotations are required for the given wheel A to go 352 m.

Answer 2

Radius of the wheel= 28cm

Circumference= 2\pi r=2\times\frac{22)

{7}\times28=176cm2πr=2×722×28=176cm

Number of rotations made by the wheel in going 352m or 35200cm =\frac{35200}{176}=200=17635200=200

Hence, the required number of rotation= 200
