Find the center and radius of the circle whose equation is x2 + y2 + 4y = 32.
And graph it

what i would say the best answer is a. 40.5

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
