Question

the diameter of a wheel is 70cm. how many times the wheel will revolve in order to cover a distance of 110m?​

Answer 1

approx 50 revolutions

Explanation:

1 revolution = πd = 70π

x revolutions = 11000

on cross multiplying we get

11000=x (70π)

x = (11/7)(100/π)

x = (22/7)×(50/π)

but π = 22/7. approx

so x = 50
