State True or False:
A solid cylinder of radius r and height h is placed over other cylinder of same height and radius. The total surface area of the shape so formed is `4pi h + 4pi r^2`

A solid cylinder of radius r and height h is palced over other cylinder same height and radius . The total surface area of the shape so formed is 4pirh + 4 pir^(2) .

Write True or False and justify your answer for the following: A solid cylinder of radius r and height h is placed over other cylinder same height and radius . The total surface area of the shape so formed is 4pirh + 4 pir^(2) .

The total surface area of a cylinder of base radius r and height h is :

State True or False and justify your answer A solid cone of radius r and height h is placed over a solid cylinder having same base radius and height as that of a cone,. The total surface area of the combined solid is pi [sqrt(r^(2) + h^(2)) +3r +2h]
