Cone volume

Take said cone and invert it.

Take a jug with measurements on the side, either litres or pints.

Fill cone with water from jug. You cxan then work out how much water is missing from the jug.

The amount missing from the jug is the volume of the cone.

Be sure to empty cone before using it for other purposes.

Of course this will be dependant on the temperature of the water and ambient air as these will have an effect on the volume in the cone. therefore temperature is a variable.

Cones

Hey Beaconsman...

The formula for it is simply 1/3rd the volume of a cylinder of the same radius and height,  as demonstrated in this useful page which includes a video showing it:

Volume of a cone

However, if you want to know how the volume of a cone is derived - how you get the formula - you'll want to look at something like this:

Deriving the volume of a cone

Hope this helps!
