A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 cm, and the bicycle wheel makes 3 full rotations before stopping.
How long is the trace of water left on the floor?
Round your answer to the nearest cm.

The trace of the water left on the floor is 566 cm.

Step-by-step explanation:

The bicycle wheel has a circular shape, therefore;

1 revolution is the same as the circumference of the wheel. So that 3 revolutions is the same as multiplying the circumference of the wheel by 3.

circumference = 2r

where r is the radius of the wheel (r = 30 cm).

Thus,

circumference = 2 x x 30

                        =

circumference = 188.57 cm

3 revolutions = 3 x 188.57

                      = 565.71 cm

Therefore, the trace of the water left on the floor is 566 cm.

inequality:

620-37.4p ≥ 450

the minimum amount of packages needed to be removed from the elevator is 5.
