Question

Please help! The formula for the volume of a cylinder is:

Answer 1

A

Explanation:

isolate r by dividing by πh. take the square root on both sides to get rid of the r^2 to make it just r

Answer 2

r =sqrt(V/ ( pi h) )

Explanation:

V = pi r^2 h

We want to solve for r

Divide each side by pi h

V/ ( pi h) = pi r^2 h/ ( pi h)

V/ ( pi h) = r^2

Now take the square root of each side

sqrt(V/ ( pi h) )= sqrt( r^2)

sqrt(V/ ( pi h) )=r
