Question

how many times a wheel of radius 28 cm must rotate to go 352 m? (Takem=2217)​

Answer 1

Step-by-step explanation:

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×

7

22

×28=176cm

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

176

35200

=200

Hence, the required number of rotation= 200
