Lets say our jar is 8 inches in diameter and 12 inches in height. To calculate the cubic inches inside a jar or other cylinder shaped object you will need to know the diameter and height of the jar then apply the following formula. You now have the volume of the cylinder in the same units you used to measure the parts.
Our calculator computes the volume of this cylinder as 1256637 cu in.
Hence V B h r2p h V B h r 2 p h To find the volume of an oblique cylinder we will use the Cavalieris Principle. Bob has a cubic suitcase with edge lengths of 2 feet and calculates the volume of soil that he can carry home with him as follows. V L p r². Cubic inches volume results.
