Frequently Asked Questions
- Can I use diameter instead of radius?
- Yes, you can input the diameter, and the calculator will automatically compute the radius as half the diameter for volume calculation.
- What formula does this calculator use?
- It uses the standard formula V = π r² h, where r is the radius and h is the height of the cylinder.
- Is the volume result precise?
- Yes, the calculator uses high-precision floating-point arithmetic with an accurate value of π to provide precise results.
- Can this tool handle irregular or tapered cylinders?
- No, this calculator assumes a perfect cylindrical shape and does not account for irregularities or tapered ends.
Key Terminology
- r (Radius)
- The distance from the center to the edge of the cylinder's base.
- D (Diameter)
- The total length across the cylinder’s base, passing through the center; optional input.
- h (Height)
- The vertical length of the cylinder from base to top.
- V (Volume)
- The amount of three-dimensional space enclosed within the cylinder.
