Question

Find the number of times a wheel of radius
56 cm must rotate to cover a distance of 264 m.​

Answer 1

Step-by-step explanation:

A wheel of radius 56 cm.

The circumference of the wheel is C=2\pi rC=2πr

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=

3.52

264

n=75n=75

Answer 2

Radius = 56 cm

Perimeter = 2 pie r
= 2 x 22 / 7 x 56
= 2 x 22 x 8
= 352 cm

Distance = 264 m
= 26400 cm

No.of times = 26400 / 352
= 75

: Wheel will rotate 75 times to cover distance of 264 m ( ANS )
