Q:
# The diameter of your bicycle wheel is 25 inches. How far will you move in two turns of your wheel? Use 3.14 for Ο.A) about 39 inches B) about 78 inches C) about 157 inches D) about 314 inches

Accepted Solution

A:

[tex]circumference \: = 2\pi \: r [/tex]

diameter = 25 inches

radius = 25/2

= 12.5 inches

= 2(3.14)(12.5)

= 78.5 inches ( for a turn )

Two turns = 78.5 inches X 2

= 157 inches

C.
