A cylinder with radius 4 and height 12 has a total surface area of 402.12 units2
The formula for the area of a rod, which is a cylinder, is given by A = 2πrh + 2πr^2, where A is the total surface area, r is the radius of the rod, and h is the length of the rod. The first term 2πrh represents the lateral surface area of the cylinder, which is the curved surface area, and the second term 2πr^2 represents the area of the two circular bases of the cylinder. By summing these two terms, we obtain the total surface area of the rod.
If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
Surface area of a cylinder = (pi) x (diameter of the circular end) x (length)

1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!
