 A cylinder has two identical flat ends that are circular and one curved side.  Volume is the amount of space inside a shape, measured in cubic units Definitions

 Diameter is the measure of a line segment from edge to edge through the center of a circle.  Radius is the measure from the center to a point on the circle.  Height is the distance between the two bases.  Pi or π = 3.14 height radius

Formula… Volume of a Cylinder = V = πr²h

A can of tomato soup is a cylinder with a radius of 3.5 cm and a height of 10 cm. What’s the volume of the can?

What if you only have the diameter? d = 8 cm h = 11 cm

 Cone – Is “pointed” like a pyramid, but its base is a circle. Volume of a Cone h r V = ⅓ Лr 2 h Area of the Base A =  r 2 Height of the cone, not to be confused with the slant height (l)
