Algebra 2?..Pleast help.?

Question

Solve for r.

I = prt

for g

S=1/2gt^2

for w

V = Lwh

for h

V=pie r^2h

Answer 1

r=I/(pt)

2S/(t^2) = g

V/(Lh) = w

V/(pie*r^2) = h

Answer 2

l = prt : l/pt = r

V = Lwh : V/Lh = w

Sorry I can't do the rest because I don't know what that little sign means.

          

Answer 3

its spelled pi not pie. pie is what you eat, pi is in math.

Answer 4

Solve for r.

I = prt - - -> divide both sides by pt

I/pt = r

for g

S = 1/2gt^2 - - -> Rewrite as

S = gt²/2 - - - > Multiply both sides by 2:

2S = gt²/2 - - > Divide both sides by t²:

2S/t² = g

for w

V = Lwh - - -> Divide both sides by Lh:

V/Lh = x

for h

V=pie r^2h ---> Divide both sides by pie r^2

V/pie r² = h

V/π r² = h
