Final answer:

The elliptical oil tank will hold approximately 8.4 quarts of oil

Step-by-step explanation:

To find the volume of the elliptical oil tank, we can use the formula:

Volume = (π * a * b * c) / 4

Where a, b, and c are the semi-major, semi-minor, and semi-vertical axes of the ellipse respectively.

In this case, we can calculate the values of a, b, and c using the given base diameters.

a = (9 3/16") / 2 = (69/16) / 2

= 69/32

b = (15 7/8") / 2 = (127/8) / 2

= 127/16

c = (14 3/8") / 2 = (115/8) / 2

= 115/16

Now, we can substitute these values into the volume formula:

Volume = (π * (69/32) * (127/16) * (115/16)) / 4

Volume = (π * 69 * 127 * 115) / (32 * 16 * 16 * 4)

Volume ≈ 1940.76 cubic inches

Since 231 cubic inches is equal to 1 gallon, we can convert the volume to quarts:

Quarts = (1940.76 / 231) ≈ 8.4 quarts

Therefore, the elliptical oil tank will hold approximately 8.4 quarts of oil.
