2) yes, you can simply plug in the information that is already given to you and you will come up with that missing side.
3) I will Plug in the missing information based on what I am given.
4) Yes, the volume of a cone is Pi*r^2*h/3 The volume of a cylinder is Pi*r^2*h and the volume of a sphere is 4/3*pi*r^3
5) I could find the volume of a cone If I am given the height and radius, or the diameter because if I have the diameter I can cut it in half and that is the radius.
The volume of a cone is pi times the radius squared times the height divided by three. The volume of a cylinder is pi times the radius squared times the height. The volume of a sphere is 4 divided by 3 times pi times the radius cubed. Does this help?
A tringular prism. The picture attached shows it- the 3 rectangular faces are the sides and bottom; the 2 triangular are the front and back. Hope this helps!!
