A geometry question

Hi guys,
In a ciricle, two radiuses form an angle and a curve. If the angle and the length of the radius are known. How do you evaluate the lenth of the curve?

Thanks

If I've interpreted your question correctly, I think you are talking about a sector of a circle--- the radii forming it and the central angle.

Let us rephrase your question ::
If the length of the circle (its circumference) corresponds too 360 degrees
then length of the sector = ---- corresponds to central angle formed.
Find the length of the sector.

I hope you see the answer now. Yet if you want the formula,
Length of a sector (curve as you call it) = (circumference*central angle)/360

P.S. All this holds good if you were referring to a 'sector'!

Thanks dude. That's the very question I want to solve.
