Describe a right circular cylinder.

Describe a right circular cone.

A container shaped like a right circular cylinder having diameter 12 cm. and height 15 cm. is full of ice-cream. The ice-cream is to be filled into cones of height 12 cm. and diameter 6 cm., having a hemispherical shape on the top. Find the number of such cones which can be filled with ice-cream.

the curved surface area of a right circular cylinder is …….. sq. units.

If the curved surface of right circular cylinder inscribed in a sphere of radius r is maximum. Show that the height of the cylinder is sqrt(2) r.

Show that when the curved surface of a is right circular cylinder inscribed in a sphere of radius R is maximum , then the height of the cylinder is sqrt(2R) .
