Q1:
No top and bottom. Just rounded side. Length in one direction, and circumference around the other direction. Imagine the pipe cut along a length and the circular pipe straightened flat.

You just need to take care of the UNITS for each of the measures.
2pi%2A%2810%2F2%29%2Amm%2A18%2Acm
5%2A18%2Api%2Amm%2Acm
Not finished! Decide what units you want: centimeters, millimeters, something else, or what? Make the needed unit conversion.
