Answer: The required remainder left after division is -12.
Step-by-step explanation: Given that the following cubic expression is divided by (x+2) :
We are to find the result after division.
<em><u>Remainder Theorem :</u></em> If a polynomial p(x) is divided by a linear factor (x-a), then the remainder is p(a).
Therefore, when f(x) is divided by (x+2), then the remainder is given by
Thus, the required remainder left after division is -12.

Check the picture below.
since the diameter of the cone is 6", then its radius is half that or 3", so getting the volume of only the cone, not the top.
1)
2)
now, the top of it, as you notice in the picture, is a semicircle, whose radius is the same as the cone's, 3.
3)
well, you'll be serving the cone and top combined, 12π + 18π = 30π or about 94.25 in³.
4)
pretty much the same thing, we get the volume of the cone and its top, add them up.
