Surface area = pi*4*6 = 75.398 square cm
The surface are of a cylinder whose radius is 10cm and height is 20cm is 1884.96cm2
A cylinder whose radius is 5 and height is 7 has a surface area of 377 units2
Total surface area: (pi*52)+(pi*5*slant length) = 240.263 square cm to 3 decimal places Note that by using Pythagoras' theorem the slant length works out as the square root of 106
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.
