<PRE><B>Question 938859</B>
Please Help!!! I&#39;m unsure how to work this problem out. I&#39;m given the answer Radius=5.67cm but I am having trouble working the problem out to get this answer.
A piece of a broken wheel is shown. It was taken to a machine shop to be replaced with a new “whole” wheel. Find the radius of the wheel if AC = 10 cm, BD = 3cm, and D is the midpoint AC of. Round to the nearest hundredth.
***
let r=radius
construct a line extending BD to the center
Connect the ends of AC to the center
You now have a right triangle with legs of (r-3) and 5 and hypotenuse=r
5^2+(r-3)^2=r^2
25+r^2-6r+9=r^2
6r=34
r=5.67 cm</PRE>
