Volume of a Cylinder, Cone, and Sphere We are learning to…find the volume of a cylinder, cone and sphere

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

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

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.

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

Volume of a Cylinder Label the BASE and HEIGHT of the cylinder below: Base of the Cylinder!

For the Volume of a Cylinder we can write: V = B(h) OR V = πr2(h)
