Question

A CD is used as a wheel on a mouse trap powered vehicle, and has a diameter of 7.45". If the mouse trap powered vehicle must travel exactly 144", how many revolutions would the wheel make? Assume that no sliding or slipping occurs between the wheel and the track surface. A. 615 C. .615 B. 6.15 D. 12.3

Answer 1

The number of revolutions the wheel would make will be 37 revolutions.  The correct option is B.

What is circumference?

The perimeter of the circle is called the circumference of circle.

Given is the wheel diameter CD = Dwheel = 7.45 inches and Length required to cover =144 inches.

For one revolution, distance equal to circumference is moved.

1 rev = π x Dwheel

1 rev = π x 7.45inches

1 rev = 23.393 inches.

No of revolution to travel 540 inches,

= 144/23.393

=6.1557 rev

≈ 6.15 revolutions.

Thus, the correct option is B.
