Step 1: From the problem we can write

Radius = r = 14 cm, height = h = 10 cm

Step 2: we know volume of a cylinder that is

Step 1: From the problem we can write

Volume = V = 3165 cubic cm and height = h = 28 cm

Step 2: we know volume of a cylinder that is

Step 4: we can simplify this and

Radius = r = 6 cm

Diameter = 2 x radius = 2 x 6 =
