Answer:

659.75 cm

Explanation:

First, find the circumference with the formula C = 2
imager

The diameter is 42 cm, so the radius will be 21 cm

Plug in the radius into the equation and solve for C

C = 2
imager

C = 2
image(21)

C = 131.95

Find how far it will roll by multiplying this by 5

131.95(5)

= 659.75

So, in 5 revolutions, it will roll 659.75 cm
