Solid Geometry

What is it?

Cylinders

A cylinder is formed by moving a line segment around a closed flat geometric figure or base.

Cones

A cone is an 3D geometric shape that tapers smoothly from a base (usually flat and circular) to a point called the apex or vertex.

It is the solid figure formed by the locus of all straight line segments that join the apex to the base. The term cone is sometimes used to refer to the surface or the lateral surface of this solid figure (the lateral surface of a cone is equal to the surface minus the base).

The axis of a cone is the straight line passing through the apex, about which the base has a rotational symmetry.

In elementary geometry, cones are assumed to be right circular, where right means that the axis passes through the center of the base at right angles to its plane, and circular means that the base is a circle. Contrasted with right cones are oblique cones, in which the axis does not pass perpendicularly through the center of the base. In general the base may be any shape, and the apex may lie anywhere. For example, a pyramid is technically a cone with a polygonal base.

The perimeter of the base of a cone is called the directrix, and each of the line segments between the directrix and apex is a generatrix of the lateral surface.

A cone with its apex cut off by a plane is a truncated cone. If the truncation plane is parallel to the cone's base, it is called a frustum. An elliptical cone is a cone with an elliptical base. A generalized cone is the surface created by the set of lines passing through a vertex and every point on a boundary.

The volume of a conic solid is one third of the product of the area of the base and the height:

V=BH/3 or in terms of calculus: $e66053d2ea2fc2ceeaaea023c5562e5e.png$

(wikipedia).

The volume of a cylinder is: π * r² * h
The volume of a cone is: π * r² * (h/3)
Surface Area of Base is: π * r²
Lateral Surface Area: π*r*s
where s is the slant height for a cone—the distance from the perimeter of the base to the vertex.
Total Surface Area is π * r * √(r²+h²)

Pyramids

Pyramids are actually special kinds of cones. Cones are often defined by their bases, so a cone with a base made up of line segments is referred to as a pyramid. So remember, all pyramids are cones, but not all cones are pyramids.

To calculate the volume and surface area for a rectangular pyramid assume the base is a square. Call the length of one side b, the slant height s, and the overall height of the pyramid h.

Area of Base is b²
Volume of Pyramid is (1/3)*b²*h

To find the lateral surface area of the pyramid, find the area of a single pyramid face (this will be a triangle) and then multiply it by four:

Area of One Face is (1/2)*b*s
Lateral Surface Area is 2*b*s
Total Surface Area is b² + 2*b*s
