The Volume of a Bottle calculator computes the volume of a bottle shaped object (see diagram). 
INSTRUCTIONS: Choose units and enter the following:
- (a) - Neck Radius
- (h2) - Neck Height (tapered neck section)
- (b) - Base Radius
- (h1) - Base Height
Volume of the Bottle (V): The volume is returned in liters (L). However, this volume can be automatically converted to many other volume units (e.g. mL, gallons or cubic inches) via the pull-down menu.
The Math / Science
Geometrically, a bottle shaped object is the combination of right circular cone with a frustum defined by base radius (a) and top radius (b) and height (h2) in between and a cylinder of radius (b) and height (h1). See diagram.
The formula for the volume of a bottle is:
`V = (pi/3)*h2*(a^2+a*b+b^2) + pi * b^2 * h1`
where:
- V = volume of the bottle
- h1 = height of cone
- h2 = height of cylinder
- b = radius of base and bottom of cone
- a = radius of top of cone
