Unit 6 Lesson 3 Surface Areas of Pyramids and Cones--

Lateral Area of Pyramid-- the sum of the areas of the congruent lateral faces             Formula: 1/2sl    or    1/2 base*height times 4

Surface Area of Pyramid-- the lateral area plus area of base

Lateral Area of Cone= pi*r*l

Surface Area of Cone= LA+ pi*r^2
