We get the idea that an "irregular sphere" is not a sphere. At that point, we know
exactly what it isn't, but not much yet about what it is. So you have to reveal a lot
more about it before anyone can calculate its volume. Like, for example, less info
about what the object is not like, and more definition of its actual shape.

First, calculate the radius. It is half the diameter. Then, to calculate the volume, use the formula: Volume = 4/3 x pi x radius3. Pi is approximately 3.1416.
volume of the cube - volume of the sphere = volume enclosed between the cube and sphere
To a first approximation, a tennis ball is a sphere. The volume of a sphere is V = 4/3 π r3, where r is the radius of the sphere. So measure the diameter of the tennis ball, divide by 2 to get the radius, and then apply the formula above. You could also measure the volume of a tennis ball by measuring the volume of water that it displaces.
The volume of a sphere with a radius of 4cm is about 268cm3
Partition (or divide) the irregular object into summation of regular objects and then calculate the volume.
Calculate the volume of a full sphere, then divide that by 2.
Volume of a sphere = 4/3*pi*radius3 in cubic units.
mass over volume
A sphere with a radius of 5 has a volume of: 523.6 cubic units.
To calculate the volume of an irregular object you will need a container with meaurements and water. Place the irregular object in your container and fill with water until the entire object is covered. Record volume A. Then remove the irregular object and record volume B. The volume of your irregulare object is equal to volume A minus volume B.
shove it up your a@@ and eat it.
water displacement
1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio
Vol = 4/3*pi*r^3 where r is the radius of the sphere.

A sphere volume = 4/3 pi r cubed
