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.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
