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. Radius is the measure from the center to a point on the circle. Height is the distance between the two bases. Pi or = 3.14 height radius Formula Volume = (area of base) x (height) A = r Rememberthe base is a circle!!! Soooo, V = rh A can of tomato soup is a cylinder with a diameter of 7 cm and a height of 10 cm. Whats the volume of the can? What if you only have the diameter? d = 8 cm h = 11 cm d = 10 cm V = 275 cm Find the height of the cylinder. Cone Is pointed like a pyramid, but its base is a circle. Volume of a Cone h r V = Bh Area of the Base A = r 2 Height of the cone, not to be confused with the slant height (l) Example 1: V = Bh = () r 2 h Area of Circle 6 in 11in The following cone has a volume of 110 . What is its radius? Solve for the missing variable Solve for the missing variable 10cm r V = Bh Volume of a Sphere 2 cm Volume of a Sphere 10 cm Volume of a Sphere 5 in Volume of a Sphere A spherical balloon has an initial radius of 5 in. When more air is added, the radius becomes 10 in. What is the difference in the two volumes? 10 in
