Calculate the circumference of the circle formed at the end of the cylinder (which is pi times the diameter) and multiply that by the height of the cylinder to get the surface area of the side of the cylinder. If you also want to add the surface area of the two circular ends of the cylinder, that is pi times the radius squared. Pi is approximately 3.14 which is accurate enough for most purposes (but many more digits are available if you need them). Let us imagine, then, that you have a cylinder that is 10" high, and 2" in diameter. The circumference of the end circles is then 6.28 and the side of the cylinder is 62.8 square inches. Each end circle has an area of 3.14 x one inch squared, which is 3.14 square inches. Two such circles are therefore 6.28 square inches (a tenth of the area of the side) and the total of the side and top and bottom of the cylinder is then 69.08 square inches.

you calculate the Area of the circle at the end of the Cylinder and then multiply it by the lenght to the second circle at the end of the cylinder Circle area= Radius*Radius* pi pi being 3.14159265
Look for the surface area of a cylinder as well as the circles and triangles

Calculate the surface area of the two circles at the ends: TTr2 x 2 = 3.14x7x7=307.72 sq. in. to calculate the surface area of the rectangle that encircles the cylinder, you need the circumference - TTd=3.14*14=43.96 in. LxW= 43.96*4=175.84 sq. in. Add the two together = total surface area of the cylinder = 483.56 sq. in.
Consider it as cylinder..
The cylinder's total surface area is about 227.77 units2

If the total area of a cylinder is 90pi (282.6) and the height is 12, the radius will be three (3).
Two hemispherical ends = 4*pi*radius2 Lateral surface area of the cylinder = 2*pi*r*lenght of cylinder Work both out separately and the sum of them will give you the total surface area in square units.
You convert the flow into m3/s and then divide that by the total area of the cylinder (m2) to give you the passing velocity in m/s. The key is finding the total area of the screen, which will depend on slot size, slot spacing, and cylinder type.
