Best Answer

It is: (2*pi*16)+(12*pi*8) = 128*pi square units

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

The surface area is 69.12 units2

Total SA = 245.04 cm2

This cylinder has a total surface area of ≈ 1,156.11 square inches.

The question does not specify what the required formula is for: the volume of an open cylinder, height, radius, surface area, etc. Furthermore, information on the total surface area of a cylinder will not provide sufficient information. A short wide cylinder can have the same surface area as a tall thin one. For example, radius 5 cm and height 4 cm or radius 4 cm and height 7.5 cm or radius 3 cm and height 12 cm or radius 2 cm and height 20.5 cm etc all have the same total surface area. But in each case the value of the other measure, for the open cylinder will be different.
