Capsule Calculator
Find volume and outer area of a cylinder with two hemispherical ends.
Formula
V=πr²(h+4r/3); S=2πr(h+2r); L=h+2r.
Radius r: 2 cm · Cylinder length h: 5 cm · Volume ≈ pi×(2 cm × 0.01 m/cm)^2×((5 cm × 0.01 m/cm)+4×(2 cm × 0.01 m/cm)÷3)×1000000 · Outer area ≈ 2×pi×(2 cm × 0.01 m/cm)×((5 cm × 0.01 m/cm)+2×(2 cm × 0.01 m/cm))×10000 · Total length ≈ ((5 cm × 0.01 m/cm)+2×(2 cm × 0.01 m/cm))×100
How to use
- Enter the radius.
- Enter the straight cylindrical length h.
- Read volume, area and total length.
Examples
- r=1 cm, h=3 cm gives V≈13.613568 cm³.
Frequently asked questions
Does h include the ends?
No. It is only the straight cylindrical section.
Can h be zero?
Yes. The capsule becomes a sphere.
What units are returned?
Volume in cm³, area in cm² and length in cm.
