When the radius is doubled, the volume of the cylinder is multiplied by 4.
Volume of a cylinder = πr^2h
So, when the radius is doubled, the new radius becomes 2r.
New volume of the cylinder = π(2r)^2h
= π(4r^2)h
= 4πr^2h
Therefore, the new volume is 4 times the original volume.
volume of a cylinder = 3.14r^2h
radius = 5
height = 4
when the radius is doubled, the volume of the cylinder is
multiplied by 2
multiplied by 3
multiplied by 4
divided by 2
divided by 4
