The volume of clay used to build a cylindrical pillar with a height of 9 centimeters is 324π cubic centimeters. The area of the base of the pillar is π square centimeters. NextReset'

Area=height times base (for some prisms including cylinders)

vcylinder=hpir²

h=height

therefor pir²=base area

vcylinder=height times aeraofbase

given

h=9

v=324pi

324pi=9 (basearea)

divide both sides by 9

36pi=areabase

the area of te base is 36pi square cm (put 36 in the blank since th pi is alredy there)
