WebApex – the intersection point of a cone, as seen in the elevation view.; Slant Height (small or large) – the hypotenuse of a cone, outside edge.The slant height is always a true length in the elevation view. Stretch-Out Angle/Arc – the angle or arc which encompasses a radial line pattern.; Frustum – a cone with the top cut parallel to the base. ... In geometry, a frustum , (from the Latin for 'morsel'; plural: frusta or frustums), is the portion of a solid (normally a pyramid or a cone) that lies between two parallel planes cutting this solid. In the case of a pyramid, the base faces are polygonal, the side faces are trapezoidal. A right frustum is a right pyramid or a right cone truncated perpendicularly to its axis; otherwise it is an oblique frustum.

WebSep 28, 2024 · Area of a lower (larger) circular base. As seen above, the curved surface area of the frustum of a cone is π l ( R + r). Area of an upper (smaller) circular base = π r 2 and area of a lower (larger) circular base = π R 2. Therefore, the total surface area of a frustum of a cone is. TSA = π l ( R + r) + π r 2 + π R 2.
