A pizza that has radius “z” and height “a” has volume Pi × z × z × a

Pi × z × z × a

If a pizza has a radius ‘z’ and a depth ‘a’, then pizza’s volume can be defined Pi*z*z*a, Because the area of a circle is Pi multiplied by the radius squared (which can be written out as Pi × z × z). Then you multiply by the height to get the total volume.
