Questions & Answers

Q: What is the formula for the volume of a cylinder?

The formula for the volume of a cylinder is V = πr²h, where V represents volume, r represents the radius, and h represents the height of the cylinder.

Q: How do you calculate the height of a cylinder given its volume and radius?

To calculate the height of a cylinder, you can rearrange the volume formula as h = V / (πr²). Substitute the known values for volume and radius, and solve for height.

Q: What units should be used for the height of a cylinder?

The height of a cylinder should use the same units as the radius. If the radius is measured in inches, then the height should also be measured in inches.

Q: Can the formula for calculating the height of a cylinder be used for any given shape?

No, the formula provided is specific to calculating the height of a cylinder. Other shapes may have different formulas to calculate their respective heights.

Summary & Key Takeaways

• The video explains how to calculate the height of a cylinder when given its volume and radius.

• It demonstrates the use of the formula for the volume of a cylinder: V = πr²h.
