# Capsule Volume, Surface Area and Circumference Calculation

Calculate the Volume, Surface Area and Circumference of capsul.

The capsule is a shape consisting of a cylinder with hemispherical ends means a sphere has been cut in half through its center and combined at both the ends of a cylinder. The radius of sphere and cylinder is same, so we can say a cylinder with two hemispherical caps on either end.

### Formulas

The formula used to calculate volume, surface area and circumference as follows:Volume

**(Vol)**= πr

^{2}((4/3)r + a)

Surface Area

**(SA)**= 2πr(2r + a)

Circumference

**(CIR)**= 2πr

Where r is radius and a is side length.
