Introduction to 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
Volume Of Spheres Practice:
Example 1
| The diameter of this sphere is 11.9 cm, so the radius is half of that, 5.95 cm. |
Example 2
You cut an orange in half and measure the radius to be 1.5 in. What is the volume of the orange half? |
Exercise 1
Find the volume of this sphere:
Exercise 2
The circumference of the circular base of this half sphere is equal to 8π cm.What is its volume?
