Repost, need help badly.

THE ANSWER IS C

Step-by-step explanation:

I believe the answer in Part A is D and in Part B is 24pi to the 3rd power

Step-by-step explanation:

For Part A, I like to think that you would need H to be alone in order to make the formula. Note that R2 is R to the second power.

V=1/3piR2H

Step 1: Use division property of equality on 1/3 ( dividing by fractions is like multiplying with just the denominator so we would just do 3V)

3V = piR2H

Step 2: Next, we will do division property of equality again, but just on the piR2 (The reason I put this in a different step is because the other one was a fraction)

3V/piR2 = H

Step 3: Flip it and then you got you answer for Part A

H = 3V/piR2

Part B:

We are now going to use the formula we just got for H, but replace the variables with the numbers ( if it shows it).

Step 1: We are going to use the rule a/b * c/d = ac/bd, it should look like this.

3*32pipi2/4

Step 2: We are going simplify it to this.

96pipi2/4

Step 3: Then we are going to use the Product Rule: x2x3= x5

96pi3/4

Step 4: Finally, simplify and now you done :) (24 π to the 3 power)

24pi3

5 /2.3= 5/  2 3/10=5/ 23/10 now u flip it which is 50/23 hope this hepls :D
