The surface are of a cylinder whose radius is 10cm and height is 20cm is 1884.96cm2
A cylinder whose radius is 6 and height is 14 has a surface area of 754 units2
A cylinder whose radius is 5 and height is 7 has a surface area of 377 units2
The curved surface area of a cylinder whose height is 14 feet and radius is 6 feet is 527.79ft2
This cylinder's height is 6 (5.98) units.

A cylinder whose radius is 2cm and height is 8cm has a total surface area of approximately 125.66cm2 {ADDED} To explain that further, the formula is pi*r^2 X h where r is the radius and h the height.
The surface area of a cylinder is 2*pi*radius*height. In this case it would be 2*pi*5*10 = 314.16
Surface area = 673.87 units2
345.6 units2
1,979.2 units2
251.3 units2
