Question 157477: I need help solving this word problem;
It says:
Use 3.14 for pie
A figure skater must trace a figure eight on the ice that consists of two perfect circles, each a radius 11ft. of How far does the skater go one time around the figure eight?

Find the perimeter of the 11 ft radius circle, then double it (for figure eight).
The perimeter of a circle is,
P%5Bc%5D=2%2Api%2AR
so the perimeter of the figure eight is,
P%5B8%5D=2%2AP%5Bc%5D
P%5B8%5D=4%2Api%2AR
In this case, R=11,
P%5B8%5D=4%2Api%2A11
P%5B8%5D=44%2Api
Using pi=3.14,
P%5B8%5D=138.16
The skater travels 138.16 feet once around the figure eight.
