# Cylinder with a Sloped Bottom Tank - Feet

Calculate the volume and surface area of a sloped bottom cylinder tank. This calculator uses feet for measurements.

##### Approximate weight of Fuel or Water
```one US gallon of water = 8.34 pounds.
one US gallon of diesel fuel = 7.1 pounds
one US gallon of gas = 6 pounds
```

In Imperial Gallons gal Imperial
In Litres L
###### Liquid Weight and Surface Area
Weight of Liquid lbs
Surface Area in Square Feet ft²
In Square Inches in²
In Square Millimetres mm²
In Square Metres

#### Calculator

1. enter the tank's diameter in feet
2. the long height of the tank in feet
3. the short height of the tank in feet
4. the weight of the liquid in pounds per US gallon

#### Results

1. the volume of the sloped bottom tank in cubic feet
2. the volume in cubic inches
3. the volume in cubic metres
4. the tank capacity in US gallons
5. the capacity in Imperial gallons
6. the capacity in litres
7. full tank liquid weight based on lbs/gal US
8. the surface area of the tank in square inches
9. the surface area in square feet
10. the surface area in square millimetres
11. the surface area in square metres

##### Formula
```V = 𝝅r²(sl)/2
where V is the volume of the tank
𝝅 = 3.14159265
r  =  half the diameter
s the short length
l the long length of the tank
```
