Question

Solve V = π r2h for h.

Answer 1

V = 2(pi)rh

Divide by 2(pi)r on both sides
V/2(pi)r = 2(pi)rh/2(pi)r

V/2(pi)r = h
h = V/2(pi)r

Answer 2

does that help you out

Answer 3

I'm confused

Answer 4

your trying to find H correct?

Answer 5

yes

Answer 6

what it is telling you to do is divide both sides of the equation by 2(pi)r to get the value of H

Answer 7

Look how the equation is written and it explains how it is done

Answer 8

okay I get what you did now

Answer 9

that is how for these equations if you are trying to find the value the correct way should be how it is done!

Answer 10

Thank you

Answer 11

Your welcome

Answer 12

I have another question. Solve P = 2(l + w) for l. What are the missing values in the table?

P w l
14 2 ?
22 8 ?

Answer 13

okay here goes and follow these is best I can help you

Answer 14

Basically distribute the 2 with the l and w, so you end up with an equation of P = 2l+2w. Since you have the values for P and W, you can just plug them in, so the only term left would be "l". Does that make it more clear?

Answer 15

all you have to do is move the constants to one side and make "l" by itself, that would be your solution to "l".

Answer 16

you had me up until you said plug in

Answer 17

place the number that is already given

Answer 18

okay

Answer 19

got it

Answer 20

yeah I got p-2w/2=l but how do I plug them in

Answer 21

type them in

Answer 22

So 8 and 14 is my answer for l
