The volume of a cylinder is 108π cm³ and its height is 12 cm. what is the length of the cylinder's radius? enter your answer in the box.

Step-by-step explanation:

The volume of a cylinder is given by the formula;

It was given that the volume of the cylinder, , and its height,

We substitute the given values into the formula to obtain;

We divide through by to obtain;

We take the positive square root of both sides to obtain;

Therefore the length of the cylinder's radius is 3cm.

the radius is 3 cm

Step-by-step explanation:

The volume of a cylinder is given by

V = pi *r^2 h

We know the volume = 108 *pi  and the height = 12

Substituting into the equation

108 * pi = pi * r^2 * 12

Divide each side by pi

108 * pi/pi = pi/pi * r^2 * 12

108  =   r^2 * 12

Divide each side by 12

108/12 = r^2*12/12

9 = r^2

Take the square root of each side

sqrt(9) = sqrt(r^2)

3 = r

sorry i dont know my friend
