. If covering 11 km the wheel of a cart makes 5000 revolutions. Find the radius of the<br> circle.
Nataliya [291]

The radius of the circle is 35 cm

Step-by-step explanation:

One revolution of the wheel of a cart = the length of the circumference of the wheel

Let the radius of the wheel be r cm

The circumference = 2 X pi X r

In 5000 revolutions the wheel covers 2 X pi X r X 5000 cm

According to the problem,

2 X pi X r X 5000 = 11 X 1000 X 100

or, pi X r = (11 X 1000 X 100)/(2 X 5000)

or, r = 110 / pi

or, r = (110 X 7)/22

= 35

Here is the answer.
