Complete the square for the given circle formula. Rmb in sch they taught you 2 types of circle formulas? Complete the square to obtain the 2nd kind of formula because what u want to find is the radius and the other formula has a raidus inside of it already which in this case is 5 given by the 5^2 on the RHS of the eqn.
