Since a cone is closely related to a pyramid , the formulas for their surface areas are related. Activity. A cone is a solid that has a circular base and a single vertex. Next, we calculate the Length of a Slant, Surface Area, Lateral Surface Area, and Volume of a cone using mathematical formulas. Visit BYJU’S to learn its formula, derivation with many solved examples. Where r is the radius of the circular base, and s is the slant height of the cone. Arthur Lee. In geometry, the formula for calculating the surface area of a right cone is: The Greek letter π ("pi") represents the ratio of the circumference of a circle to its diameter. Surface Area of a Cone Formula SA = B + LA, where SA is known to the surface, B describes the AREA of the base, and also LA refers to a lateral location. Curved Surface Area of Cones (Combined Version) Activity. A cone with its height and slant height.
