If the height of a right circular cone be 4.8 cm and its diameter of base 4 cm, then the slant height of the cone will be

The height of a right circular cone is 12 cm and its volume is 100 pi c c , then find the radius of the cone.

The radius of a right circular cone is 7 cm at its vertical angle is 60^@ . Find the curved surface area of the cone.

If the base radius and height of a right circular cone are 28dcm. And 21dcm., then the slant height of the cone is

The height of a right circular cone is 30 cm . A small part of the cone is cut off from the above part of the cone with the help of a plane parallel to the base of the cone. If the volume of the small part be (1)/(27) part of the volume of the original cone , then at what distance above the base of the cone , it has been cut off ?

If the numerical values of the area of the base and the volume of a right circular cone of radius 4cm be equal , then the slant height of the cone is

Show that height of the cylinder of greatest volume which can be inscribed in a right circular cone of height h and semi vertical angle alpha is one-third that of the cone and the greatest volume of cylinder is 4/(27)pih^3tan^2alphadot
