Help with finding an area of a sector

Hello, I am struggling to find the area of a sector when given the arc length s and central angle (Theta). I have the forumlas for it but the formula does not account for arc length s so I assume there is some type of exchange for another value. Any help would be appreciated.

Here is an example. s =.3456ft, Theta = 73.61, A=?

Re: Help with finding an area of a sector

If you're working in degrees, rather than radians, then:





Once you have r, you have the area of the circle:



And the area of the sector is:
