Go through this material,  AS BEST YOU CAN,  before you view the video tutorials that follow.

I’m hoping you actually DO this activity.
If you measured a sphere and have a radius, you can use that to calculate the surface area and volume of your sphere.
Your teacher would likely be able to check your work.

If you want to see how this would be done,  you can watch the video that follows, and I will use a radius of 10 cm so you have a specific example to work with.

?  How can you use these materials and formulas to determine the volume and surface area of any spherical ball?
