1. Lesson #1 Volume of a Cylinder We are learning to…find the volume of a cylinder

2. Volume  Definition The number of cubic units needed to fill a given space  Geometric Shapes Cylinder Cone Sphere

3. Cylinder  A three dimensional figure with two parallel, congruent bases connected by a curved lateral surface  http://www.youtube.com/watch?v=FLtkVS8bAUY http://www.youtube.com/watch?v=FLtkVS8bAUY  https://www.youtube.com/watch?v=Zd_2OW-IBww https://www.youtube.com/watch?v=Zd_2OW-IBww

4. Previous Formulas Learned Area and Circumference of a Circle Formula to find the area of a circle:The formula to find the circumference of the circle: Area is the space inside of an object. Circumference is the perimeter (length outside) of a circle.

5. Cylinder  Formula B = Area of the base h = Height r = Radius = Pi = 3.14159…..(irrational number use calculator unless told otherwise)

6. Volume of a Cylinder  Label the BASE and HEIGHT of the cylinder below: Base of the Cylinder! Height of the Cylinder!

7. Volume of a Cylinder  For the Volume of a Cylinder we can write: V = B(h) OR V = π r 2 (h)
