Question 179829: How many square feet of fencing material do you need to make an open cylinder 4 feet across and 4 feet high? Answer by nerdybill(7384) (Show Source):
You can put this solution on YOUR website! Basically, the area is circumference of cylinder times height.
.
Circumference = (pi)D
where
pi = 3.14
D = diameter
.
Circumference = (3.14)4 = 12.56
.
Area = 12.56(4) = 50.24 square feet
