To find the volume of the cylinder we must first find the height and radius of the cone.
Volume of a cone = (1/3)*(pir^2h) Volume of a cylinder = pir^2h If you look carefully you will notice that the only difference between the two is that the volume of the cone is multiplied by (1/3) thus if multiple the cone's volume of 150 by 3 we get the volume of the cylinder containing it.
