Day 3 unit 1

Objective: "surface area of prism, pyramid, cylinder, cone, and sphere"
How to find surface area of:
Prism:3D figure with rectangle sides. Area of 2 bases plus area of sides
Pyramid: Area=area of base plus area of all sides
Cylinder: 2pi times r2+2pi times r times height
Cone: pi times diameter times height
Sphere: 4 times pi times r2

Quiz:

1. How do you find the surface area of a rectangular prism?

2. How do you find the surface area of a pyramid?

3. What is the equation to find the surface area of a sphere?

4.  How do you find the surface area of a cone?

5. How do you find the surface area of a cylinder?

Quiz answers

1. Area of 2 bases plus area of sides

2. Area of base plus area of all sides

3. To find the surface area of a sphere, you multiply pi times 4, then take that and multiply that by radius squared. It is just finding the area of a circle, and multiplying that by 4. 

4. To find the surface area of a cone you pi r2 +pi r l.

5. To find the surface area of a cylinder you use the formula 2pi r2 + 2pi r h
