A wheel with radius 3 cm is being pushed up a ramp at a rate of 6 cm per second. The ramp is 730 cm long, and 150 cm tall at the end.
How far does the wheel travel in one rotation?
the circumference of the wheel is just 2pi*r
To find out how far the wheel travels in one rotation, we need to calculate the circumference of the wheel.
The circumference of a circle can be calculated using the formula: C = 2πr, where C is the circumference and r is the radius of the circle.
In this case, the radius of the wheel is given as 3 cm. Therefore, the circumference of the wheel is:
C = 2π * 3 cm
C ≈ 6π cm
Now that we have the circumference, we know that the wheel travels approximately 6π cm in one revolution.
