We are given equation V = r²h.
Let us break it into parts to get the correct variation.
V = r²h could be written first V= r² × h.
And we could break it in two different proportions:
V ∝ r² can be read as V is directly proportional to r².
V ∝ h can be read as V is directly proportional to h .
Non of the variable r² or h in denominator.
<em>When we have any variable in denominator, it's an inverse variation and if we don't have any variable in denominator, it would be a direct variation.</em>
<h3>Therefore, we can say V = r²h is a direct variation.</h3>
Begin by multiplying everything by 3 to get rid of the fraction. That gives us
. The rule is when you divide by a negative, the direction of the sign changes, so we will end up with
. Because there is a line under the inequality sign, the circle is closed. So your choices are the second, fourth, and sixth.
