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.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
