(has an internal diameter of 0.35m)
(and is 3.0m long.)
The pipe's shape is cylinderlike.
Formulas involving cylinder-shaped (closed at both ends) objects:
1. Cross-sectional area (the area of the base only): A =
2. Circumference (perimeter of the circle):
4. Surface area:
Use what I gave you and try to solve. If you face problems, come back.
EDIT: Please remember that this is an OPEN-ended pipe. Don't count the surface area of the base/top twice.
