Acar wheel is 56 cm in diameter. a. how far does the car go in one revolution of the wheel?
b. how far does it go in 100 revolutions?

The car moved 175.84 cm in one revolution

The car has moved 17584 cm in 100 revolutions

Solution:

Given that car wheel is 56 cm in diameter

diameter = 56 cm

To find: distance traveled in one revolution of wheel

Usually wheel is of circular shape

one revolution of wheel = circumference of circle

The circumference of circle is given as:

We know that,

diameter = 2(radius)

So the circumference becomes:

substitute = 3.14 and d = 56 cm

Thus the car moved 175.84 cm in one revolution

B. How far does it go in 100 revolutions

Distance covered in 100 revolutions = 100 x Distance covered in 1 revolution

Thus the car has moved 17584 cm in 100 revolutions
