If the slant height and the base radius of a cone are 10cm and 8cm respectively,then find curved surface area and total surface area.

The radius of a cone is 5cm and vertical height is 12cm. Find the area of the curved surface.

The radius of a cone is 3cm and vertical height is 4cm. Find the area of the curved surface.

The radius and slant height of a cone are 5 cm and 10 cm respectively . Find the ratio of the curved surface area to the total surface area of cone.

The diameter of a cone is 14cm and its slant height is 9cm. Find the area of its curved surface.

The radius and vertical height of a cone are 5 cm and 12 cm, respectively. Then, its lateral surface area

The radius and slant height of the cone are 5 cm and 10 cm respectively. Find the curved surface area. (pi=3.14)
