4
A cylindrical water tank holds L of water. The volume of a cylinder is given by V = 3.14r2h. How much water (in L) could the tank hold if the radius was doubled?

5
A cylindrical water tank holds L of water. The volume of a cylinder is given by V = 3.14r2h. How much water (in L) could the tank hold if the height was doubled?

6
A cylindrical water tank holds L of water. The volume of a cylinder is given by V = 3.14r2h. How much water (in L) could the tank hold if the radius was doubled and the height halved?
