What is the volume of a sphere cut by a plane?
We can calculate the volume of a section of a sphere using the formula, V = (1/3)πh2(3R - h), where, height h of the spherical section, and radius R of the sphere from which the section was cut.
As you have to find the volume of sphere between these two planes, you really have to find the volume of the spherical cap.
Volume of spherical cap = πh2(3R−h)3 where h is the height of the spherical cap and R is the radius of the sphere.
R=1,h=(1−√32).
Solving it, you get the volume as π3(2−98√3).
Why is the volume of a sphere 4 3 pi r 3?
Quickly stated, it comes from the fact that if you took two cones with similar measurements to the sphere, it would end up that the volume of those two cones would equal the volume of the sphere.
Using a bit of mathematical wizardry the 4/3 ends up being derived from this fact.
