Ramesh has three containers.
A) Cylindrical container A having radius r and height h
B) cylindrical container B having radius 2r and height 1/2 h, and
C) cuboidal container C having dimensions r r r
The arrangements of the containers in the increasing order of their volume is
(i)The volume of the cylindrical container having radius r and height h = πr2h
(ii)The volume of the cylinder container with radius 2r and height
= π (2r)2 × × h = 2πr2h
(iii)The volume of the cuboidal container having dimension
= r2 h
From parts i ,ii and iii ,we have the following order C,A,B.
