Question

Solve the formula V =pir^2h for r.

Answer 1

I hope this helps.

Explanation:

Heres my Explanation this is the correct explantion.

Step 1. Divide both sides by π

Vπ=π

r2hπ

=r2h

Step 2. Divide both sides by h

Vπh=r2h

h

=r2

Step 3. Take ±√ both sides

±√Vπh=r

Step 4. Radius, r, is not a negative value, so just keep the positive

r=√Vπh

Answer 2

Explanation:

When we are solving a formula for a variable, that means we mean to set the variable to one side and everything else on the other side

`V = \pi r^(2) h\\(V)/(\pi *h) =r^(2) \\r = \sqrt{(V)/(\pi *h) }`

Hope that helps!
