Q&A for How to Calculate the Volume of a Cylinder

The radius is half of the diameter. If you know the diameter, just divide that by two to find the radius.

Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.

Measure the tank and calculate the volume like a normal cylinder. If it's irregularly shaped, just fill it with water until it's full, and however much water you filled it is its volume.

You can't. You need at least one of either height or radius. Since the volume V of a right circular cylinder is given by V = πr²h. This leads to: h = πr²/V ; r = +√(πh/V). What the above expressions mean is that you need to know two of the variables to determine the other. Note also that if V > 0, then both r and h must also be greater than 0.

Divide by 231.

You can divide the diameter by 2 to get the radius, square the radius and multiply it by pi and get the area of the base, but since you don't have height or volume, you wouldn't be able to solve the equation v=bh.

The volume of cylinder: r squared times pi times height= 1.2 times 1.2 times pi times 20 = 1.44 times pi times 20 which is around 90.48 meters squared. Volume of water: r squared times pi times height = 1.2 times 1.2 times pi times 1 = 1.44 times pi which is around 4.52 meters squared.

Divide by 100.

Yes.

That's true, where "b" is the area of the circular base of the cylinder, and "h" is the cylinder's height, as explained in the final step in the above article.

Multiply the volume by 3 and divide by 4. Divide again by pi. Find the cube root of that number. Double it. That's the diameter.

Calculate the volume of the tank as shown in the article above. Divide the volume (in cubic inches) by 231 to find U.S. gallons.

Divide cubic inches by 46,656.

Measure the height and the diameter of the pot. Calculate the volume using the height and half the diameter, then use the conversion factor to convert to quarts. One quart equals roughly 58 cubic inches or 946 cubic centimeters.

You would have the same mathematical formula, your units would simply be different. Normally volume is measured in cubic centimeters, but you could calculate it in inches or feet, then use a converter to find the volume in cubic centimeters. I would advise that you convert your measurements into centimeters first and then use your volume formula.

Divide cubic feet by 27.

Four times the first radius.

Divide millimeters by 1,000.

If you know the volume in cubic inches, divide by 231. If you know the volume in cubic centimeters, divide by 3,785.4.

If the volume is expressed in cubic centimeters, divide by 1,000.

Calculate the volume. If you're using inches, divide the volume by 231 to find gallons. If you're using feet, divide by 0.134 to get gallons. If you're using centimeters, divide by 3,785.4.

Volume is base area multiplied by height.

Multiply pi by the square of the inside radius, then multiply by the length of the pipe.

Calculate the volume in cubic centimeters, and divide by 1,000.

Divide cubic inches by 14.4375.

Divide the circumference (perimeter) by pi. That gives you the diameter. Divide by 2. That's the radius. Square the radius and multiply by pi. That gives you the area of the circular end. Multiply that area by the height. That's the volume.

The volume of a sphere is (4/3)(πr³), where r is the radius.

A cubic centimeter is the same thing as a milliliter.

There are 1,000 liters in a cubic meter.

You cannot. You need other measurements. Knowing only the height, you would only be able to work out probabilities.
