If the total area of a cylinder is 90pi (282.6) and the height is 12, the radius will be three (3).
244.92
Total surface area is 176 units2
Total surface area including the two end pieces = (2*pi*radius2)+(2*pi*radius*height) in square units.
It is the area of the circle (pi Rsquared=100PI) times the height 20 total area is 2000PI
If the total area of a cylinder is 90pi (282.6) and the height is 12, the radius will be three (3).
A cylinder with radius 4 and height 12 has a total surface area of 402.12 units2
A cylinder that has a radius of 1 and a height of 10 has a total surface area of 69.12 units2
A cylinder with a 7cm radius and 3cm height has a total surface area of about 439.82cm2

A cylinder with a radius of 1 meter and a height of 10 meters has a surface area equal to 69.12m2
Total SA = 245.04 cm2
Total surface area is 176 units2
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.
Total SA = 1,256.6 cm2
Total SA = 678.58 units2
