By Brit Caswell 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? Vocabulary Altitude – the perpendicular segment that joins the bases Height – the length of an altitude 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 Pg 700 #1 Use this net to find the surface area of the rectangular prism. Find the Surface Area What is the name of this shape? Cylinders – have two congruent, parallel bases which are circles Describe how to find the lateral area and the surface area of a cylinder! 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? Find the surface area Find the LA and SA Name this shape! Why does a pyramid use the slant height when a triangle uses the perpendicular height? Can you describe why using a net? Find the LA and SA Cone – A solid that has one base and a vertex that is not in the same plane as the base Find the LA and SA Find the LA What is this figure named?
