Your answer is:-
Step-by-step explanation:
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 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
Therefore, 75 times a wheel of radius 56 cm must rotate to cover a distance of 264 m.
