Alright. In class we learned about volume and surface area of spheres. So a sphere is basically a bunch of spheres grouped together at different angles that creates a 3-d circle called a sphere.
Basically all you have to do is multiply 4 by pi, then by that short little line from the center to the outside (radius) squared, and you get your surface area.
Volume is basically the same thing just you multiply by 4/3 instead of 4 and the radius is cubed.
Now that you think you know what you need to do good luck.
