What is the formula for the volume of a cone?

• Volume = 1/3 * π * r^2 * height

• Volume = π * r * height

• Volume = 1/2 * π * r^2 * height

• Volume = π * r^2 * height

What does the 'r' represent in the formula for the volume of a cone?

• Circumference of the base

• Area of the base

• Diameter of the base

• Radius of the base

Why do we multiply the volume formula by one-third for a cone?

• To simplify the calculation

• To adjust for the circular base

• Because a cone is three times the volume of a cylinder

• Because a cone is one-third the volume of a cylinder with the same base and height

If the radius of a cone is 7 cm and the height is 8 cm, what is the first step in calculating the volume?

• Square the radius

• Multiply the radius by the height

• Multiply the radius by π

• Divide the radius by two

What is the result of 7 squared in the context of calculating the volume of a cone?

• 14

• 49

• 56

• 21
