Understanding the Volume of a Cone

What is the first step in solving a problem involving the volume of a cone?

• Measure the slant height

• Find the diameter

• Draw a diagram of the cone

• Calculate the surface area

Which formula is used to calculate the volume of a cone?

• 1/2 × base × height

• π × radius² × height

• 2 × π × radius × height

• 1/3 × π × radius² × height

What is the approximate value of π used in the calculations?

• 3.00

• 3.75

• 3.14

• 3.50

After substituting known values, what is the next step in solving for the radius?

• Multiply the constants

• Divide by the height

• Subtract the volume

• Add all terms together

How do you find the radius once you have the radius squared?

• Multiply by two

• Add the height

• Take the square root

• Divide by the volume
