Volume of a Cylinder

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

Definition 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:

A r 2 Area is the space inside of an object. The formula to find the circumference of the circle: C d Circumference is the perimeter

(length outside) of a circle. Cylinder Formula 2

VV r h Bh 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!

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