Answers
Step-by-step explanation:
As per the given statement:
Aliaa is skating down a ramp. The wheels on her skateboard have diameters of 60 mm.
⇒ Diameter of wheel(d) = 60 mm
The distance around the circle or wheel is equal to the circumference.
The number of revolutions(n) completed by rotating a wheel in a given distance
i.e,
n=
Circumference of wheel =
Substitute the given value we get;
Circumference of wheel = mm
To find the distance Aliaa travels when her skate board wheels make 20 revolutions.
⇒ Distance covered =
Substitute the given value we have;
Distance covered = = mm
Therefore, the distance Aliaa travels when her skate board wheels make 20 revolutions is, 3768 mm
