The shape of the lower part of a solid object is like a hemisphere and the upper part like a right circular cone . If the surface area of the two parts be equal , then find the ratio of the length of radius and height of the cone .

A solid is hemispherical at the bottom and conical above. If the surface areas of the two parts are equal, then the ratio of its radius and the height of its conical part is____

A solid is hemispherical at the bottom and conical (of same radius) above it . If the surface areas of the two parts are equal then the ratio of its radius and the slant height of the conical part is

If the radii and volumes of a solid right circular cone and a solid sphere be equal, then what will be the ratio of the length of diameter of the sphere and the height of the cone ?

The lower and upper part of a solid object are hemispherical and conical respectively. If the area of total surface of 2 parts are equal, then find the ratio of the height of two parts of this object.

The lengths of radii of a solid right crcular cone and a solid sphere are equal. If their - volumes be also equal, then find the ratio of the radius of the sphere and the height of the cone.

The lower part of a radius tent is a right circular cylinder and its upper part is a right circular cone . If the diameter of base of the tent be 105 metre , the height of the cylindrical part is 3 metre and the slant height of the conical part be 53 metre , then what quantity of canvas will be needed to make the tent ?

A solid is in the shape of a cone mounted on a hemisphere of same base readius. If the curved surface areas of the hemisphere part and the conical part are equal then find the ratio of the radius and the height of the conical part.

The curved surface area of a right circular cone is sqrt(5) times of its base area . Find the ratio of the height and the length of radius of the cone.

The lateral surface area of a cylinder is equal to the curved surface area of the cone. If the radius is same, then find the ratio of the height of the cylinder and slant height of the cone.

The area of curved surface of a right circular cone is sqrt 5 times that of the base of the cone, find the fatio of the height and the radius of the base of the cone.
