For each of the five wheels in the robotics kit, find the linear distance traveled in one
revolution in centimeters. To do this, record measures for each wheel three times and
report the average of the distances. If working in a group of three, each student should
contribute a distance value.

1.
First, estimate the diameter of each wheel by measuring and then calculate the diameter
using the average linear distance from the table.(Show work in the space provided.)
