Cone

Curved surface area of Cone P is seven times the curved surface area of Cone Q. Slant height of Cone Q is seven times the slant height of Cone P. What will be the ration of the area base of Cone P to the area of the base of Cone Q?

An ice cream cone consists of a right circular cone and a hemisphere that has the same base as thatof the cone.The height of the cone is 8cm and the diameter of its base is 6cm. The volume of the ice-cream in the cone is

A right circular cone is sliced into a smaller cone and a frustum of a cone by a plane perpendicular to its axis. The volume of the smaller cone and the frustum of the cone are in the ratio 64 : 61. Then their curved surface areas are in the ratio

The radius of right circular cone A is (1)/(5) of the radius of right circular cone B, and the height circular cone A is (1)/(4) of the height of right circular cone B. What is the ratio of the volume of right circular cone A to the colume of right circular cone B ?

A solid spherical metal ball of diameter 72 cm is melted and recast into small solid cones of diameter 6 cm and height 6 cm. Find the number of cones that can be formed using this melted metal. A)3456 cones B)3600 cones C)3568 cones D)3200 cones

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 ?

Given a sphere,a cone is constructed so that the cone and the sphere have the same volume,but the total surface area of the cone is k xx that of the sphere,where k is determined so that there is a unique cone satisfying this property.Then k equals:
