Total surface area `= 2 pi R h + 2 pi r h + 2 pi(R ^2-r^2)`.

Total surface area quad =2 pi Rh+2 pi rh+2 pi(R^(2)-r^(2))

Total surface area =(2 pi rh+2 pi r^(2)) sq.

Curved (lateral) surface area = (External surface areal) (Internal surface area)= 2 pi Rh+2 pi rh=2 pi h(R+r)sq. units.

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 cylinder with radius r and height h is closed on the top and bottom.Which of the following expressions represents the total surface area of this cylinder? 2 pi r(r+h) (b) pi r(r+2h)pi r(2r+h)(d)2 pi r^(2)+h

If h,G,V,T are respectively the height,curved surface area,volume and total surface area of a cylinder,then prove that: V(pi h^(2)+C)+(V^(2))/(h)=h(T^(2))/(4)

Asolid 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]

If the diameter of the base of a closed right circular cylinder be equal to its height h, then its whole surface area is 2 pi h^(2) (b) (3)/(2)pi h^(2)(c)(4)/(3)pi h^(2)(d)pi h^(2)

Surface area of each base =pi(R^(2)-r^(2))sq . units.
