# Volume of Cones – Lesson 7.4

*Please email your work to me*

**Learning Tool**: Big Ideas Accelerated textbook, page 318

**Goal**: I can find the volume of a cone by using a formula

**Background Notes**: **Please click on the link **

Recall the volume of a cylinder = (Area of Base) x (Height)

Notice that a cone is structurally the same as a pyramid

It would then make sense that the volume relationship between the cone and cylinder is the same as the relationship between the pyramid and prism: Pyramid/Prism and Cone/Cylinder

Volume of a cone = 1/3 (volume of a cylinder with same base and same height)

*You can remember the volume formulas for all of the solids we have seen with just two concepts*

**Volume of Prisms and Cylinders**

**Volume = (Area of Base) x (Height)**

**Volume of Pyramids and Cones**

**Volume = 1/3 (Volume of Prism or Cylinder with same base and height)**

**Textbook Notes** –

*Please read through the Key Idea and the following examples beginning on page 318 of your Big Ideas Accelerated textbook*
