I'm sorry, 3 squared 2 makes no sense to me. Three squared times 2 is 18. Three squared is 9. Nine times 2 is 18. The above is fast and simple, but not up to my standards. If by the question you mean 32*2 then the answer is (3*3)*2 So 3x3=9. 9x2=18. On the other hand if you meant What is 3 squared as in 32 then the answer is simply 3*3. Please be as specific as possible in your questions involving mathematics as possible. Anything squared is the number times itself. Cubed is times itself 3 times. Example: 33=27 and so on. Math requires precision. Without that precision you will not get a correct answer, ever. And you have to know the proper order in which to do any equation. I hope this helps.
the volume of a cylinder is (pi)r squared times the height, same as a circle but plus the height so the answer here would be ((pi) x 1) squared x 5. or 5 pi squared
SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h
