Volume of a Cylinder How much will I hold?
Definitions 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 Radius is the measure from the center to a point on the circle. Height is how tall the cylinder is. Pi or π = 3.14 radius height
Finding the Volume • r = 5 cm • h = 11 cm • Formula… • V = (πr²) · h • V = 3.14 · 5 · 5 · 11 • V = 863.5 cm³ radius height
Finding the Volume • What if you only have the diameter? • 1. d = 10 cm (divide by 2) so r = 5 • h = 11 cm • Formula… • V = (πr²) · h • V = 3.14 · 5 · 5 · 11 • V = 863.5 cm³ radius height
Now you try one! A can of tomato soup is a cylinder with a radius of 7 and a height of 20 cm. What’s the volume of the can? V = (πr²) · h V = 3.14 · 7 · 7 · 20 V = 3,077.2 cm³ YUM!!!
