128cm^3

Step-by-step explanation:

With the given cone and the give formula, we can easily plug in the numbers provdied with one step right before.

While the height and diameter is given, we must use radius when working with volume of a cone, and radius is half of the diameter. In this case, the radius would be 4 cm

Plugging in the rest of the numbers, we get (3 * 4^2 * 8) / 3 which comes to a grand total of 128cm^3

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
