Looks like the very definition for a rational number
The answer to this question is 7
For this case we have a factored expression, of a second degree equation:
(
To find the solutions:
we add 3 to both sides of the equation:

We subtract 8 on both sides of the equation:

Thus, the solutions of the equation are:

Answer:

<h3>
Answer: Choice A) 1344π cubic units</h3>
Work Shown:
r = 8 = radius
h = 63 = height
V = volume of the cone

Side note: You could write the symbol π as "pi" without quotes.
