Unit 9 Lesson 3
Clean sheet: Titled “Lesson 2: Prisms and Cylinders”

Naming Pyramids “Base + Pyramid”

Volume of a Prism: Bh where B is the area of the base.
 Volume of a Pyramid: 1/3 a Prism

Volume of a Cylinder: Bh where B is the area of the base (pi r^2)
 Volume of a Cone: 1/3 a Cylinder
Examples 14: Find the Volume.

Lateral Area: Area of the faces of a polyhedron not including bases.
 l is Slant Height

Surface Area of a Pyramid: 1/2 lp +B

Surface Area of a Cone: 1/2 lp + B

But the perimeter of a circle is the circumference or 2pi r. and the B=pi r^2

So the SA of a Cylinder: l(pi r)+(pi r^2)
Examples 58: Find the Lateral and Total Surface Area.
