One of the lessons we learned this week was about the surface area and volume of a sphere, and how to find these with limited information.

First you need the formulas for both the surface area and the volume..

Now to use these formulas, you need to replace the given numbers and variables with the information from the question… examples of this in play are…

Also it can be difficult to find the surface area or volume if you don’t have the radius or diameter… for example you have the surfaçe area but need to find the volume… and vice versa, so here are some examples of how to do that…
