Homework Help: Geometry

Posted by Temperance on Monday, June 14, 2010 at 1:05am.

What is the radius if:
degree of measurement of arc=30
length=1/3xy(pi)
My answer was 8xy.

degree of measurement of arc=40
length=8/9(t)(pi)
My answer was 9t.

degree of measurement of arc=18
length=6(y)pi
My answer was 45y.


These are the questions I missed, along with my answers. I would be grateful if someone could explain what I did wrong and work out the problem, so that I may understand it fully. Cheers!
