Normally, I'm not bad with my math formulas but, in my current lesson I have having some issues. Can somebody please provide me with a (non-complicated) formula for finding the surface area and lateral are for both cylinders and prisms? Any help is much appreciated! Thanks

Answer 1

cylinders are easy:
Consider a can of height h, and radius r

Visualize taking off both lids of a tin can, you would have 2 circles.
Now cut the "sleeve" along the height then fold it flat, and you would have a rectangle of length 2πr and height h
So the surface area
= 2πr^2 + 2πrh or 2πr(r + h)

Prism is much too vague of a term, since there are so many different kinds of prism

Now, if you Google something like
"surface area of triangular prism" you will get an overwhelming amount of information.
Just become selective.
It helps if you can visualize your shape separated into flat surfaces, called a net, then finding the areas of the different shapes.

what does that have to do with math
