Answer:
1. w = V/lh 2. pi = c/D
Explanation:
1. To solve for w you just have to isolate it from the l and h that are attached to it -->
V = lwh, divide both sides by lh to isolate w
/lh /lh
w = V/lh
2. To solve for pi, it's the same as #1, just isolate pi from the c/ that's attached to it -->
D = c/pi, multiply both sides by pi
(pi) (pi)
D(pi) = c, divide by D to isolate pi
/D /D
pi = c/D
