Find the center and radius of the sphere x 0x + y + 4y + z - 0z = 60 Center: ( Radius: Write down an (in)equality which describes the solid ball of radius 9 centered at (-2, -10,-9). It should have a form like x + y + (z 2) 4 >= 0, where you use one of the following symbols . The first blank is for the algebraic expression; the drop-down list gives the (in)equatilty. 0.
