Answer:
The ellipse is not the graph of a function.
Step-by-step explanation:
If you can draw a vertical line on the graph that intersects the graph in two or more points, the relation shown is <em>not a function</em>.
A vertical line will intersect the ellipse at two points (unless it is tangent to an end of the major axis), so the ellipse is not the graph of a function.
A tilted or slanted cylinder has the same volume as its equivalent right cylinder, provided that
(a) the two bases of the tilted cylinder are parallel,
(b) the base areas of the tilted and right cylinders are equal,
(c) the vertical height of the right and tilted cylinders are equal.
This fact can be verified by slicing the tilted cylinder into thin, flat washers, as in integral calculus.
Because all 3 conditions are satisfied, the volume of the tilted cylinder is 450 cm³.
Answer: 430 cm³
