What's the volume formula for a cone? And the area formula,

The cone volume v = 1 / 3 sh s is the bottom area of the cone, h is the height of the cone, R is the bottom radius of the cone
Side area of cone = 1 / 2 × generatrix length × circumference of cone bottom = π × radius of cone bottom × generatrix length
Surface area of cone = bottom area + side area s = π R ^ 2 + π RA (note a = generatrix)
