A cylinder that has a radius of 1 and a height of 10 has a total surface area of 69.12 units2
A cylinder that has a diameter of 20 and height of 26 has a total surface area of 2,261.95 units2
This cylinder has a total surface area of ≈ 1,156.11 square inches.
An open cylinder has zero volume. Its surface area is 4(pi)rL, wherein r is the radius of the cylinder and L is the length. A closed cylinder has a volume of L(pi)r^2. (That is, L times pi times r-squared.) Its surface area is 2(pi)rL + 2(pi)r^2.
Total surface area is 245.04 units2
