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.
water displacement
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.
The water displacement of a sphere can be calculated using the formula for the volume of a sphere, which is V = (4/3)πr^3, where r is the radius of the sphere. The volume of water displaced by the sphere is equal to the volume of the sphere when it is submerged in water.
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.
