Question

the diameter of the wheel of the of a car is 98 cm how many Revolution will it make to travel 6160​

Answer 1

Given, diameter of the wheel = 98 cm

thus, radius = (98 ÷ 2) cm

= 49 cm

Let the number of revolutions be 'x'

Now,

Distance covered =circumference of wheel × no. of revo.

=> 6160 = (2 × 22/7 × r) × x

=>

$\frac{6160 \times 7}{2 \times 22 \times 49}$

=> x = 2

hence, the no. of revolution is 2.
