To find the volume of a sphere, follow this simple formula (which took a brilliant ancient Greek mathematician named Archimedes years to derive):
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?
Find the volume of this sphere:
The circumference of the circular base of this half sphere is equal to 8π cm.What is its volume?
