The volume of a cylinder that is 12 feet long but has a radius of 5 feet is: 942 cubic feet.
It is a rectangle and its perimeter is 12+12+6+6 = 36 feet
Area = 0.5*(15+7)*12 = 132 square feet
22 x 12 = 264 square feet
By multiplication and so 12 times 12 = 144 square feet
12 feet=3,657.6 millimeters
