1. 11.2, 11.3 Surface Areas of Prisms, Cylinders, Pyramids, and Cones
By Brit Caswell

2. Objective and EQ
Students will visualize, sketch, construct, and use various 3-D geometric figures to solve problems.
What are two different ways that 2-D shapes and 3-D solids are related?
Describe at least two methods you can use to find the surface area and volume of a solid?

3. Vocabulary

4. Altitude – the perpendicular segment that joins the bases
Height – the length of an altitude

5. Lateral area (LA) – the sum of the areas of the lateral faces Surface area (SA) the sum of the lateral area and the area of the two bases

7. Pg 700 #1
Use this net to find the surface area of the rectangular prism.

8. Find the Surface Area
What is the name of this shape?

9. Cylinders – have two congruent, parallel bases which are circles

11. Describe how to find the lateral area and the surface area of a cylinder!

12. Pg 702 #3
A cylinder has a height of 9 cm and a radius of 10 cm. What is the surface area of the cylinder in terms of pi?

14. Find the surface area

15. Find the LA and SA
Name this shape!

18. Why does a pyramid use the slant height when a triangle uses the perpendicular height? Can you describe why using a net?

19. Find the LA and SA

20. Cone – A solid that has one base and a vertex that is not in the same plane as the base

22. Find the LA and SA

24. Find the LA
What is this figure named?
