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.
