you have a steel cylinder 5ft in diameter and 6in thick there are 40 bolt holes 1in in diameter also 6in thick the steel weighs 490 pounds per cubic foot and there are 1728 cubic in, in a cubic foot how much does the cylinder weigh.

step-by-step explanation:

c

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
