Question

Find the number of times a wheel of radius 56cm must rotate to cover a distance of 264m (Take π =22 ÷7

Answer 1

75 time wheel must be rotated

Answer 2

75 times a wheel of radius 56 cm must rotate to cover a distance of 264 m.

Step-by-step explanation:

Given : A wheel of radius 56 cm must rotate to cover a distance of 264 m.

To find : The number of times a wheel rotate ?

Solution :

A wheel of radius 56 cm.

The circumference of the wheel is  $C=2\pi r$

C=2\times \frac{22}{7}\times 56

C=352\ cm

The circumference in m,

1 cm=0.01 m

352 cm=3.52 m

A wheel rotate to cover a distance of 264 m.

The number of times wheel rotate is given by,

$n=\frac{264}{3.52}$

$n=75$

Therefore, 75 times a wheel of radius 56 cm must rotate to cover a distance of 264 m.
