Question

The diameter of wheel of surjeet taxi is 42cm . Find how many complete revolution will it take to cover 396m

Answer 1

Step-by-step explanation:

The find the amount of revolutions required to complete 396 meters, we need to find how many meters each revolution can complete. This is also equal to the wheel’s circumference (distance around circle).

Circumference is calculated:

C = 2πr (r = radius)

Radius is half of the diameter thus radius = 42/2 = 21cm

Now,

C = 2π x 21

Therefore, C = 42π

Therefore, C is 131.94689145077…

We will round that to 132 cm.

Now we want the measurements to be the same so we change 132 cm to 1.32m.

To find the total amount of revolutions (aprox), we will divide 396 by 1.32

which equals about 300 revolutions.
