Question

the diametre of a wheel of a bus is 112 cm. how many revolutions will it make to cover 1 km 56 metres​

Answer 1

Answer:

It will make 300 revolutions.

Step-by-step explanation:

First we need to find the circumference of the wheel by using the formula 2πr after we use this formula we will get the circumference of the wheel as 352 cm

we then need to convert cm to m by dividing the circumference by 100

352 / 100 = 3.52 m

and so we get the circumference in meter as 3.52 m.

then we need to convert the distance asked to cover into meters also.

1 km 56 m = 1000m + 56m = 1056 m

now, to get the no. of revolutions made by the wheel in order to cover the given distance, we need to divide the given distance by the circumference of the wheel.

no. of revolutions = distance to be covered / circumference of the wheel

                              = 1056m / 3.52m

                              = 300 revolutions.
