Question

The number of revolutions a wheel of diameter 40cm makes in travelling a distance of 176 m is

Answer 1

Answer:140

Step-by-step explanation:

Given diameter = 40cm

2r=40

Distance covered by wheel in one revolution = circumference of the wheel

So circumference of wheel=2πr=40π

Then, revolutions in 176m = 17600cm

will be 17600/40π=140

Answer 2

Answer:

Here is the answer

Step-by-step explanation:

You need to find the circumference/Perimeter of the wheel first and then divide the total distance travelled by the perimeter of the wheel.
