Question

2.
A wheel of radius 14cm rotates 5 times. Find the total distance covered by the
wheel.(Take π = 22 upon 7
​

Answer 1

Answer:

To find : How many times will a wheel of radius 14 cm have to rotate to cover a distance of 22 m?

Solution :

A wheel of radius 14 cm

Circumference of the wheel is C= 2\pi rC=2πr

C= 2\times \frac{22}{7}\times 14C=2×

7

22

×14

C= 88\ cmC=88 cm

It cover a distance of 22 m.

Convert into cm,

1 m = 100 cm

22 m=2200 cm

The number of times wheel rotate is given by,

\text{Revolutions} =\frac{\text{Distance}}{\text{Circumference}}Revolutions=

Circumference

Distance

\text{Revolutions} =\frac{2200}{88}Revolutions=

88

2200

\text{Revolutions} =25Revolutions=25

Therefore, 25 times will a wheel rotate to cover a distance.
