The Sphere is a three-dimensional analogue of a circle. This worksheet help you to understand how to calculate sphere volume and surface area.
sphere volume formula:
Sphere Volume = (4/3) π r3
sphere surface area formula:
Square Surface Area = 4 π r2
Example problem:
Calculate the Area & volume of the Sphere whose Radius is 5
Sphere Volume = (4/3) π r3
= (4/3) x 3.14 x 53
= 523.8095
Sphere Surface Area = 4 x3.14 x 52
= 314.2857
The area & volume of the sphere is 314.2857 & 523.8095
When you try such calculations on your own, this sphere calculator can be used to verify the results of your calculations.
