At a Glance - Volume of Spheres
To find the volume of a sphere, follow this simple formula (which took a brilliant ancient Greek mathematician named Archimedes years to derive):
Volume of a Sphere = 4/3π x radius cubed = 4/3πr3
The diameter of this sphere is 11.9 cm, so the radius is half of that, 5.95 cm.
You cut an orange in half and measure the radius to be 1.5 in. What is the volume of the orange half?
