The radius and height of a right solid circular cone are `r` and `h` respectively. A conical cavity of radius `r/2` and height `h/2` is cut out of this cone. What is the whole surface area of the rest of the portion

If the base radius and height of a right circular cone are r and h respectively, then the volume of the cone is

If the base radius and height of a right circular cone are 2R and H respectively, then the area of total surface of the cone is

The radius of the base and the height of a right circular cone are 7 cm and 24 cm respectively. Find the volume and the total surface area of the cone.

Find the volume of a right-circular cone of base radius r and height h.

The radius of a right circular cone is 3 cm and its height is 4 cm. The total surface area of the cone is

Radius and slant height of a solid right circular cone are 35cm and 37cm respectively,Find the curved surface area and total surface area of the cone.

If a hemisphere of radius r unit is placed on one end of a right circular cyllinder of radius r unit and height h unit and a right circular cone of radius r unit and height h unit on the other end of the cylinder , then the total surface area of the new solid object will be pir (2h+2r+sqrt(h^(2)+r^(2))) sq - unit
