If you have a computer (I assume you do or you wouldn't be HERE) you have a calculator of sufficient capacity. You merely need to know the formula.
where c is the length of the chord and a is the length of the arc, radius = (a² + 1/4c²)/2a Plug in your values, do the math, and there you are..... so..... square a and add to memory. square c and multiply x .25 and add to memory. recall memory and divide by two, then divide by a. you are done.
