Question

Kameron's unicycle wheel has a spoke length of 16 inches.

16 in.
Approximately how many inches of ground does Kameron cover in 3 full rotations of the unicycle wheel? (Use 3.14 as an approximation of pi.)

Answer 1

301.44 inches

Explanation:

The spoke is from the center of the wheel to the edge, so its length is the radius, or 16 inches.

You want to find the distance that one rotation will take you, so you need the wheel's circumference.

Circumference = 2πr

2 x 3.14 x 16 = 100.48

100.48 inches is the distance of only 1 full rotation, so you just need to multiply 100.48 by 3 to get the distance of 3 rotations.

100.48 x 3 = 301.44
