Solve the formula:
c/2 = A/r solve for r.


Any help would be appreciated.

If 12/2 = 18/3, then does 3=(18*2)/12?

if a/b = c/d, then ad = bc : crisscross multiplication

so a = bc/d or d = bc/a or b = ad/c or c = ad/b

try it with pka's 12/2 = 18/3: 12 * 3 = 18 * 2, right?
and 12 = 18 * 2 / 3, 3 = 18 * 2 / 12, 18 = 12 * 3 /2, 2 = 12 * 3 / 18; ok?

your problem will work the same.
