Question

A water glass is in the shape of a right conical frustum which has a lower base of radius 2 inches and an upper base of radius 3 inches.If the distance between the bases is 6 inches, what is the volume of the glass ?

Answer 1

6+x/x=3/2,x=12inch

volume of the conical frustum=

I/3πR 2H-1/3πr 2h=

'/3πx3x3x12 -1/3πx2x2x6=

28π =88 inch 3

Vol. of the conical frustum is =88 inch 3
