To find the surface area of a cylinder, you need to add the area of the two bases (which are circles) and the area of the curved surface (which is a rectangle that has been rolled into a cylinder shape).
Surface area of cylinder = 2πr² + 2πrh
(where r is the radius and h is the height)
Alternatively, you can use the diameter (d) instead of the radius, but it will require an additional step to convert the diameter to the radius.
For example, if a cylinder has a radius of 5 cm and a height of 10 cm:
Surface area = 2π(5)² + 2π(5)(10)
Surface area = 2π(25) + 2π(50)
Surface area = 50π + 100π
Surface area = 150π
So, the surface area of the cylinder is 150π square units, or approximately 471.24 square units if you use a calculator and round to two decimal places.

Wait, ca I ask this again? I didn't ask right the first time.
Sure, please feel free to rephrase your question.

I apologize for the confusion in my previous response. The dimensions you have provided do not include the radius or diameter of the cylinder. Without this information, it is not possible to calculate the surface area of the cylinder. Please provide the radius or diameter of the cylinder.
