Find the amount of empty space within a cylinder containing three solid spheres, where each sphere has a radius of 3 cm. (Volume of a sphere = 4/3πr^3)

Step-by-step explanation:

cylinder's height=3 * (diameter of sphere) = 3*6=18 cm

radius of cylinder=3 cm

volume of cylinder=π r²h=π (3) ²*18=162 π cm³

volume of sphere=4/3 π (3) ³=36 π cm³

reqd. empty space=162 π-3*36π=54 πcm³
