I need help with the question below. A bicyle tire has a diameter of 24 inches. If a tire rotates for 20 revolutions about how far has the bike rider ridden? Use 3.14 for pi. I know to find the circumference you would do 24 x 3.14 which equal 75.36. I'm not sure what to do with the number of revolutions though. Do you multiply 75.36 times 20? Thanks

Yes. Multiply 75.36 inches by 20 to find how many inches the rider has ridden.

Yes. Multiply 75.36 inches by 20 to find how many inches the rider has ridden.

To find out how far the bike rider has ridden, you need to calculate the circumference of the bicycle tire and then multiply it by the number of revolutions.

You've correctly calculated the circumference of the tire using the formula C = πd, where C is the circumference, π is approximately 3.14, and d is the diameter. So in this case, the circumference of the bicycle tire is 24 × 3.14, which equals 75.36 inches.

Now, to find how far the bike rider has ridden, you multiply the circumference by the number of revolutions. In this case, the tire rotates for 20 revolutions. So you need to multiply 75.36 inches by 20:

75.36 inches × 20 = 1,507.2 inches

Therefore, the bike rider has ridden approximately 1,507.2 inches.
