4/3pir^3
The best way to find the volume of an irregular solid is to submerge it in a liquid and see how much the liquid rises. You can also use calculus and tripple integrals, but that gets really sticky.
to obtain the ratio of surface area to volume, divide the surface area by the volume.
By dividing the area into the volume: width = volume/area
Surface Area: 2πr2 + 2πrh Volume: πr2h

You need the area to find the volume of an object.
The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.
finding the volume of a cone
Find the area of the base, find the height of the pyramid. Volume = (1/3)*(area of base)*(height)
to obtain the ratio of surface area to volume, divide the surface area by the volume.
By dividing the area into the volume: width = volume/area
That would be a volume, not an area...
i am not sure you can...
Surface Area: 2πr2 + 2πrh Volume: πr2h
1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio
