Volume of a cylinder and radius

In summary, when calculating the radius of a cylinder, the volume needs to be converted into cubic inches in order to use the equation for radius in inches. This is necessary because the cylinder length is already in inches and using different units can lead to confusing and incorrect results. Therefore, it is important to use consistent units throughout the formula.

Ok so i know the equation for the volume of a cylinder and the equation for calculating the radius. But when calculating the radius does the volume need to be converted into cubic inches or can it stay as imperial fluid ounces.
Thanks

It needs to be converted into cubic inches first if you want the radius in inches.

Use the volume units that are needed. Convert the length units to inch equivalents or convert the length units to their imperial fluid ounce unit.
Looking at what you described, you want a radius value, and you have the volume and cylinder length. Convert the volume into cubic inches! Now you have a formula for radius in inches. Your cylinder length should already be in inches.

Sigh. See what happens when people do not use SI units! The dimensional analysis gets very complicated (and when people skip that part, the answer makes no sense).
 

Related to Volume of a cylinder and radius

1. What is the formula for calculating the volume of a cylinder?

The formula for calculating the volume of a cylinder is V = πr²h, where V is the volume, π is approximately 3.14, r is the radius, and h is the height of the cylinder.

2. How do you find the radius of a cylinder?

The radius of a cylinder can be found by measuring the distance from the center of the circular base to the edge of the base. Alternatively, if you know the diameter of the cylinder, you can divide it by 2 to find the radius.

3. Can the radius of a cylinder ever be negative?

No, the radius of a cylinder should always be a positive value. It represents the distance from the center of the base to the edge of the base, and distance cannot be negative.

4. How do you find the volume of a cylinder if the radius is not given?

If the radius is not given, but the diameter is known, you can divide the diameter by 2 to find the radius. If neither the radius nor the diameter is given, you will need more information (such as the height or surface area) to calculate the volume.

5. Can you use the same formula to calculate the volume of any cylinder?

Yes, the formula V = πr²h can be used to calculate the volume of any cylinder, regardless of its size or dimensions. Just make sure to use the correct units for the radius and height.
