Question

A wheel has a radius of 28 cm. If it does 50 revolutions, what distance will it travel?

Answer 1

Answer:

87.96 meters to the nearest cm.

Step-by-step explanation:

First find the circumference of the wheel

= 2 π r

= 2 π * 28

= 175.929 cm.

So one revolution is  equivalent to travelling 175.929 cm.

50 revolutions = 175.929 * 50

= 8796.46 cm.

= 8796.46  / 100

= 87.96 m (answer).
