Surface area and volume formulas for geometry Cone, prism ~
Conical surface area: Let the radius of the base circle be R, the height of the cone be H, and the generatrix be l (the side expanded figure is the fan-shaped radius). Because l=Sqrt (R^2+H^2), there is a side area =πRl total area =πR (l+R), the volume of the cone V=1/3ShS is the base area of the cone, h is the height of the cone, and r is the volume of the base radius prism of the cone.
Surface area of the cone: Let the radius of the base circle be R, the height of the cone be H, and the bus be l (the radius of the drawing is the fan-shaped radius). Because l=Sqrt (R^2+H^2), the side area be=πRl, the total area of the cone be=πR (l+R), the volume of the cone be=πR (l+R), V=1/3ShS, the bottom area of the cone, h be the height of the cone, and r be the volume of the base radius of the cone.
