Step-by-step explanation:
The discriminant tells you where the graph of the parabola goes through the x-axis, if at all. If the discriminant is negative there are no real zeros and the parabola does not cross or touch the x-axis; if the discriminant is positive the parabola will go through the x axis in 2 places; if the discriminant is 0 the parabola will touch the x-axis in 1 place. Our discriminant is 0 since the parabola only touches the x-axis but does not go through.

Step-by-step explanation:
Usually when you try and find the area you would multiply but you don't have one of the numbers to multiply, so what is the oppisite of multiplication? Divison. You would divide the area by the highth. so it would be 4.5 divided by 1.8. 4.5 divided by 1.8 equals 2.5. And to make sure your answer is correct you would multiply 1.8 times 2.5 wich does equal 4.5. The highth is 1.8, the Length is 2.5, and the are is 4.5
The answer is e because the volume is 54 pi mm^3. This is because the volume of a cylinder is pi * r^2 * h.
