Funnel Tank Volume and Surface Area - Metres

Calculate the volume and the surface area of a funnel shaped container or tank. The funnel tank here has the shape of an upside-down cone with a circular top that comes to a point. This calculator uses metres for measurements.

Approximate weight of Fuel or Water
```one litre of water = 1 kilogram
one litre of diesel fuel = 0.832 kilogram
one litre of gas = 0.75 kilogram
```
`Note: measurements used in the calculation are diameter lengths, not radius lengths!`

Formula
```V =𝝅R²h/3
where V is the volume of the tank
𝝅 = 3.14159265
R half the tanks' diameter
h the height of the tank
```
