Geometry- Cones
Question | Answer |
---|---|
A three dimensional figure that consists of a circular base and a curved lateral surface that connects the base to a single point not in the plane of the base, called the vertex | Cone |
The perpendicular segment from the vertex to the plane of the base | Altitude |
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 |
