**Solve problems involving surface area and volume of right pyramids, right cones, spheres and related composite solids (VCMMG365)**

**LO: To find surface area and volume of Right Cones**

**Know:**

- the definition of radius and π
- the definition of volume and surface area
- the definition of a right cone

**Understand:**

- That formulas can be used to quickly find the surface area and volume of right cones.

**Do:**

- I can find the surface area and volume of right cones.

**Right Cone**

A **right cone ** is a 3-D shape that has the **apex**** (point of the pyramid) directly above the center of a circular base**.

An **oblique cone** is a 3-D shape where the apex** doesn’t **not line up **directly above the **center** of a circular base**.

**Volume of Right Cones**

To find the volume of a right cone, you need to multiply the radius by π then by the square root of the sum of the radius squared and height squared.

**Surface Area of Right Cone**

To find the surface area of a right cone, you need to multiply the radius by π then by the square root of the sum of the radius squared and height squared.
