Answer:
Well we need to start with one concept. When the wheel makes one full rotation, the unicycle will travel a distance equivalent to the wheel’s circumference. When we figure out the circumference, we will know how far it will travel in one rotation. We will then need to multiply that value by 4 to see how far it will travel in 4 rotations.
The wheels circumference is equivalent to 2*pi*radius. Or C=pi*diameter.
Pi=3.14
Diameter=12inches
C=(3.14)*(12inches) =37.68 inches
That's one revolution. Now let's multiply by 4 to get the distance traveled in 4 revolutions.
(37.68 inches) * (4 revolutions) = 150.72 inches traveled in 4 revolutions.
150.72 is already rounded to the nearest hundredth.
