Volume of Sphere Demonstration
thingiverse
The base radius and the height of the cylinder are designed to be equal, r. Therefore the volume of the cylinder is given by pi r^2 r = pi * r^3 If we make 4 such cylinders, then the total volume will be 4 pi r^3 Then we made a sphere with radius equal to the base radius of the cylinder. Print 3 such spheres with 0% infill such that water can be poured into them. The water poured out from these 3 spheres should be able to fill the 4 cylinders, therefore the volume of each sphere is given by 4 pi r^3 /3 = 4/3 pi r^3 https://youtu.be/8LbeQutuRfY
