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

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

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.

Write the ratio of total surface area to the surface area of a cylinder of radius r and height h

The total surface area of a solid hemisphere of radius r is

If each side of a cube is a, then its lateral surface area is ………. Sq. units.

A solid cylinder has the total surface area 231 sq. cm. If its curved surface area is 2/3 of the total surface area, then the volume of the cylinder is:

The total surface area of a sphere is 8pi square unit. The volume of the sphere is

The surface area of a sphere is 100pi cm^(2) . Find its volume.
