Net
Properties
* two parallel bases that are congruent circles
Formula
V = 𝜋𝑟 2 ℎ
Radius – radius of one of the circular bases
Height – perpendicular distance between the
parallel bases
* circular base , curved surface, one vertex
Cone
SA = 2𝜋𝑟 2 + 2𝜋𝑟ℎ
V=
Lateral surface – the curved surface of the cone
height- distance from the vertex to the center of
the base
𝜋𝑟 2 h
3
SA = 𝜋𝑟 2 + 𝜋𝑟ℓ
Slant height – distance from the vertex to a point
on the circumference of the base
* curved surface
* every point on the surface is equal distance from
the center
Sphere
Radius – distance from the center of a sphere to
any point on its surface.
Pyramid
(Example of a square pyramid)
V=
4𝜋𝑟 3

SA = 4 𝜋𝑟 2
𝐵ℎ
3
* One polygonal base (can be triangle, square,
pentagon, etc.)
𝑉=
* Three or more triangular faces which meet
at a vertex
B = area of the base
*when sliced parallel to the base, the cross
section has the same shape as the base
(Example of net of square * when sliced perpendicular to the base, the
cross section is a triangle
pyramid)
