Identify the variation as direct, inverse, joint or combined. V =π r²h

inverse
combined
direct
joint

direct

Step-by-step explanation:

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.

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.

Therefore, we can say V = r²h is a direct variation.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

good luck on ur quiz test or homework. have a good day : )
