If a tricycle tire travels in one rotation, then the tricycle travels in a distance where d is equal to the circumference of the wheel. This means that we have to use the circumference formula for this problem.
The circumference formula goes like this:
(where “r” means radius of a circle and “π” is 3.14.)
We can write the following formula for finding the distance traveled by a tricycle when its single wheel makes a complete rotation.
Therefore, the tricycle will move 188.4cm (Letter D) in one rotation.
Hope it helps!
