Question

A tire turns through an angular displacement 628 radiant. How many revolutions did it turn?

a) 100 revolutions
b) 50 revolutions
c) 200 revolutions
d) 25 revolutions

Answer 1

To calculate the number of revolutions the tire turned, we need to convert the angular displacement from radians to revolutions.

Step-by-step explanation:

To calculate the number of revolutions the tire turned, we need to convert the angular displacement from radians to revolutions. Since 1 revolution is equal to 2π radians, we can use the formula:

Number of revolutions = Angular displacement / (2π)

Plugging in the given values, we get:

Number of revolutions = 628 / (2π)

Simplifying this, we find that the tire turned approximately 100 revolutions.
