Good question if only because it approximates. I imagine you might have been told to do the question in your head.
Area = pi r^2
r = d/2
r = 4/2
r = 2 feet
pi = 3
Area = 3 * 2 * 2 = 12 square feet <<<<<< Answer.
Somewhere in 1 Kings Ch 7, the Bible makes reference to pi being 3. It's a pretty good estimate considering the number system the Bible used.
No, there can not be negative amplitude because it is just the distance between the max and the midline or the minimum and the midline.
I see where you might be confused because for instance in the trig equation:
y = -3 sin (.5(x-

/2)) -1, there is a negative in front of the amplitude. However, when finding the amplitude, you take the absolute value of a.
