Question

The volume of a cylinder is

1323 π cm cubed 3. The height of the cylinder is 27 cm. What is the radius of the​ cylinder?

Answer 1

radius is 7 cm

Explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the volume is 1323 pi and the height is 27

1323 pi = pi r^2 * 27

Divide each side by 27 pi

1323 pi /27pi = pi r^2 * 27/ 27 pi

49 = r^2

Take the square root of each side

sqrt(49) = sqrt(r^2)

7 = r
