I NEED HELP ASAP FOR THIS MATH QUESTION

Answer 1

Answer:

C

Step-by-step 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

$\frac{s}{\pi} - {r}^{2} = l$

Answer 2

Answer:

The answer is C.

Step-by-step 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.
