for a cylinder it is
(PI)*r*2*cos(B) + 2*r*h*sin*(B)
Where r is radius
B is the angle between the normal to the cylinder face and the normal to the plane of projection

Surface area of a cylinder = (pi) x (diameter of the circular end) x (length)
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.
The volume of a cylinder is found by multiplying the area of its base times its height.
The surface area of a cylinder with the radius of 2 and height of 3 is 62.83 units2
A cylinder with radius 4 and height 12 has a total surface area of 402.12 units2
