WebbMidterm Exam I, Calculus III, Sample B 1.(6 Points) Find the center and radius of the following sphere x2 +y2 +z2 6x+4z 3 = 0. Completing the squares: 0 = x2 + y2 + z2 6x+ 4z 3 = (x2 6x+ 9) + y2 + (z2 + 4z+ 4) 3 9 4 = (x 3)2 + y2 + (z+ 2)2 16: So, the equation of the sphere is (x 22) 2+y +(z ( 2)) = 42, the center is (3;0; 2) and radius 4.
