The volume of a cylinder can be expressed as V=πr2h, where r is the radius, and h is the height of the cylinder.

olga_2 [115]

<em>Note: You missed to add the answer choices, so I am solving the overall procedure to determine the radius of the cylinder so that you could easily figure out the right choice.</em>

Answer:

The radius of the cylinder:

$r\:=\:\sqrt{\frac{v}{\pi \:h}}$

Step-by-step explanation:

The volume of a cylinder is represented by the formula

V=πr²h

here

r is the radius

h is the height

The radius of the cylinder can be computed using the formula of the volume of a cylinder

V = πr²h

r² = V / πh

Taking square roots

$r\:=\:\sqrt{\frac{v}{\pi \:h}}$

Thus, the formula of the radius of the cylinder.

$r\:=\:\sqrt{\frac{v}{\pi \:h}}$

Therefore, the radius of the cylinder:

$r\:=\:\sqrt{\frac{v}{\pi \:h}}$
