Question

I NEED HELP ASAP FOR THIS MATH QUESTION

Answer 1

C

Explanation:

`s = \pi .l \: + \pi. {r}^(2)`

Make the term including 'l' stand alone.

`s - \pi. {r }^(2) = \pi.l`

Now make L stand alone by dividing through by pi.

`\frac{s - \pi. {r}^(2) }{\pi} = l`

This is the same as

`(s)/(\pi) - {r}^(2) = l`

Answer 2

The answer is C.

Explanation:

First, you want to isolate the variable you are look for, 'l'. First subtract [pi]L from both sides. Then subtract S from both sides.

-[pi]L+S=[pi]r(superscript)2 ->

-[pi]L=[pi]r(superscript)2-S

Now, since you have your variable 'l', you want to remove the [pi] away from your variable. To do this, multiply by negative 1 divided by pi, or -1/[pi].

L=S-r(superscript)2.

Therefore, the answer is C.
