Finding the Volume of Cones

What is the formula for the volume of a cone?

• V = 1/3 * B * H

• V = Pi * r^2 * H

• V = 2 * Pi * r * H

• V = B * H

What does the 'B' in the cone volume formula represent?

• The diameter of the base

• The circumference of the base

• The area of the base

• The radius of the base

In the formula for the volume of a cone, what does the 'H' represent?

• The height of the cone

• The area of the base

• The radius of the base

• The diameter of the base

What is the volume of a cone with a base area of 19.625 and a height of 10, rounded to the nearest hundredth?

• 62.18 cm^3

• 65.42 cm^3

• 58.87 cm^3

How do you find the radius if you are given the diameter of the cone's base?

• Divide the diameter by 2

• Square root the diameter

• Square the diameter

• Multiply the diameter by 2

If a cone has a diameter of 7 and a height of 12, what is the first step to find its volume?

• Multiply the diameter by Pi
