Step-by-step explanation:
we have
we know that
a)<u> in the interval </u>----> (0,∞)
If the value of x increase the value of y increase
so

If the value of x increase the value of y decrease
so
Is a inverse variation
therefore
Is a combined variation
To find the volume of a cylinder, you use this formula:
V =
h
Plug in your numbers,
V = (3.14 *
) * 13
Exponents:
V = (3.14 * 64) * 13
Parentheses:
V = 200.96 * 13
Multiply:
V =
