Simpler than your problem but...

Two cars start at the same point and drive in the opposite direction. They drive 8 miles each and then both make a right turn and drive 6 miles each. How far apart are they?

28 miles

28 miles

No, it’s 20 (2 times the square root of the sum of 6 squared and 8 squared).

The openings at each end of the cylinder are 8 feet across.

You're saying - two at each end. The diameter is going to be effected by the inside walls, floor and ceiling that touch the doors.

2 doors, 8 ft. what separates the doors into two? Then say, there's two feet on either side of the doors, now we have twelve ft. by 40?

OR - is there ONE door at each end adding up to two?

No, he means openings like the ends of a paper towel roll. You need to calculate the circumference and multiply by the length to get the square footage of the metal required to make the cylinder.

Okay, thanks. His description seemed odd.

1,004.8 roughly, using 3.14 as pi.

3.14 x 8 = 25.12

25.12 X 40 = 1,004.8.

Final answer.
