If x be the volume, y be the area of the base and z be the height of a cone then the value of x / yz is 3.

If V be the volume, R be the radius of the base and H be the height of a right circular cone, then H = ____

If V be the volume, R be the radius of the base and H be the height of a right circular cone, then H = ____.

If the volume of a right circular cone is V cubic unit, the base area is A sq. unit and the height is H unit, then find the value of

In a right circular conical tent, 11 persons can stay. For each person, 4 sq. m space in the base and 20 cu.m. air are necessary. Determine the height of the tent put up exactly for 11 persons.

Curved surface area of a right circular cone is 154√2 sq cm and radius of the base 7 cm. Find its vertical angle.

The height of a right circular cone is twice the radius of the base. If the height were seven times the diameter of the base then the volume of the cone would have been 539 cu cm more. Find the height of the cone.
