A cone is a geometrical figure with one curved surface and one circular surface at the bottom. The top of the curved surface is called the apex of the cone. An edge that joins the curved surface with the circular surface is called the curved edge of the cone.Know More
If the apex of the cone lies just above the center of the circular base, it is called a right circular cone. Oblique cones do not have the apex directly above the center of the base. The curved height or slant height of the cone is called the lateral height of the cone.
The cone may be hollow or solid. The curved surface area of the cone is calculated by the formula A=?rs where r is the radius of the base, and s is the slant height of the cone. The total surface area of the cone is given by A=?r(r+s).Learn more about Shapes
The volume of a cone is found by multiplying the area of the circular base by the height of the cone, and then dividing the product by 3. The area of the base is found by taking the square of the radius and multiplying it by pi.Full Answer >
A cone only has one flat surface, its circular base. Its other surface is a curved one that extends from the base to the apex.Full Answer >
Examples of items that are cone-shaped or conic in design are the waffle cone, paper megaphone, traffic cone, funnel, Christmas tree and party hat. Some decorative items, such as lamp shades, earrings or brooches, are also shaped like coes. The hives of bald-faced hornets display a conic shape.Full Answer >
Calculate the surface area of a cone by first finding the area of the slanted section on top and the area of the base. Add these two areas together to get the total surface area of the cone.Full Answer >
