A solid cylinder of radius r and height h is placed over other cylinder of the same height and radius. Find the total surface area of the shape so formed.
let radius = r
height = H
now
when it is placed over another cylinder
radius = r
height = 2 H
as we know
total surface area
height = H
now
when it is placed over another cylinder
radius = r
height = 2 H
as we know
total surface area
