Question

S=2兀r2+2兀rh solve for h

Answer 1

What the given equation is about ?

Answer 2

how about you solve it for us and show us your solution, we will check if you are wrong along the way

Answer 3

I dont know how..i have to solve for h

Answer 4

how could you not know how?

Answer 5

I mean that why i need help

Answer 6

do you have any idea what to do at all, or you want us to replace your teacher for you?

Answer 7

Im trying to help my friend with her algebra 2 homework

Answer 8

Wow your nice.

Answer 9

A = B + C
to solve for B, we isolate it by subtracting C on both sides of the equation giving us
A-C = B + C - C
performing the operation, we end up with
A - C = B

the same concept occurs in your problem. first, identify the operations, obtain their opposite in order to isolate that which you are looking for.

Answer 10

-.-

Answer 11

Im still lost

Answer 12

the opposite of multiplication is division and addition is subtraction. and vice versa

Answer 13

if you are lost then, you are missing a lot of fundamental knowledge prior to arriving at the current level of math you are taking.

Answer 14

Thanks, i mean not really im a freshman taking algebra 2 honors and its a hard class

Answer 15

let us put those letters A, B and C into actual numerical values.

25 = 18 + 7

if we want to look for 18 we isolate 18 by subtracting 7 on both sides of the equations
25 - 7 = 18 - 7

performing the operation we will obtain
25 - 7 = 18

continue

18 = 18


this is the simplest way of explaining the concept you are missing. instead of letters they became actual values and it could be more letters and constant values - values that do not change like pi, which we normally refer to simplest value as 3.14

Answer 16

wrong answer. you are to inquire that which you do not understand, but you have to be specific

Answer 17

S=2兀r^2+2兀rh

you want to look for the value of h
the h is stuck together with 2兀rh
but for the time being we can imagine 2兀r^2+2兀rh like B + C
we want to isolate B first, so you need to subtract B which is 2兀r^2

can you at least perform that task and show me what you've come up with?

Answer 18

Sure

Answer 19

S-2兀r2= S= 2兀rh

Answer 20

Wrong

Answer 21

S-2兀r2=2兀rh

Answer 22

Do i divide 2兀r?

Answer 23

I think you got the idea
now let us break down 2兀rh to isolate h
remember that 2兀rh is all multiplication and we need its opposite, which is division
would it make sense if we divide 2兀r on both sides of the equation

Answer 24

see I think you're a smart kid! how about you do what you thought you should

Answer 25

I just gave low self esteem

Answer 26

what do we have next?

Answer 27

S-2兀r2/2兀r=h

Answer 28

What do you mean by what do we have next?

Answer 29

yes I mean what you have now is what I was asking

Answer 30

So thats correct?

Answer 31

I have another problem
