Formulas for a Cone
MetricFormula
Surface AreaA=pi*r(squareroot(r^2+h^2) +r*h)
VolumeV=(1/3)*pi*r^2*h
Slant LengthS=squareroot(r^2+h^2)
Implicit Equationr*(x^2+y^2)/h = (z-z0)^2
Parametric Equationx=((h-u)/h)*r*cos(theta), y=((h-u)/h)*r*sin(theta), z=y, 0<=u<=h, 0<=theta<=2*pi

Conic

Conic means having to do with a cone, such as a conic section; cone-like in shape; or is short for conic section. Conical means cone-like in shape, such as a conical frustum.
