Length of the altitude Height of the Cone
What type of cone intersects the base of the cone at its center? Right Cone
What type of cone does not intersect the base of the cone at its center? Oblique Cone
Formula for surface area for a right cone? S = LA+ B or S = Πrl + Πr(squared)
Formula for volume of a cone? V = 1/3BH or V=1/3Πr(squared)h
Formula for lateral area? LA= 1/2Cs
