Cylinder Volume Formula:
| From: | To: |
The cylinder volume formula calculates the amount of space inside a right circular cylinder. It's one of the fundamental formulas in geometry and has practical applications in engineering, architecture, and various scientific fields.
The calculator uses the cylinder volume formula:
Where:
Explanation: The formula multiplies the area of the circular base (πr²) by the height of the cylinder to determine its total volume.
Details: Calculating cylinder volume is essential for determining capacity of containers, pipes, and tanks. It's used in manufacturing, construction, fluid dynamics, and many engineering applications where cylindrical shapes are common.
Tips: Enter the radius and height in the same units. Both values must be positive numbers. The result will be in cubic units of the input measurement.
Q1: What if my cylinder is not a right circular cylinder?
A: This formula only works for right circular cylinders where the sides are perpendicular to the base. For oblique cylinders, different calculations are needed.
Q2: Can I use different units for radius and height?
A: No, both measurements must be in the same units to get a correct volume calculation in cubic units.
Q3: How accurate is the π value used in the calculation?
A: The calculator uses PHP's built-in M_PI constant which provides π to about 14 decimal places, ensuring high precision.
Q4: What's the difference between volume and capacity?
A: Volume is the total space occupied, while capacity typically refers to how much a container can hold, which may be less than the total volume.
Q5: Can this calculator be used for hollow cylinders?
A: For hollow cylinders (tubes), you would need to calculate the volume of the outer cylinder and subtract the volume of the inner hollow space.
