Question

A rolling pin has a diameter of 5 inches. If Lin rolled across the table and it made 35 rotations how far did it travel?

Answer 1

Answer:

2.22 rotations

Step-by-step explanation:

First, have to multiply the diameter by Pi. 5 * π = 15.7

15.7 is the circumference because the formula for circumference is d * π = c (diameter=d, circumference=c)

Next, 35/15.7 is 2.22.

You divide the 35 by 15.7 because if 15.7 inches is one rotation, then you want to see how many rotations fit into 35.

Answer 2

Answer

so to find out how far it traveled im pretty sure u have to multiply the circumference by 35 (amount of rotations) giving you 549.5

pls tell me if im wrong :,)
