1. The net of a cylinder consists of two circles and a rectangle:
Total surface area of a cylinder= 2πr ^{2} + 2πrh
2. The net of a cone consists of the circular base along with the curved surface area:
3. To find the surface area of a sphere with radius r, use the formula:
The base radius, , of a cone is the same as the radius of a hemisphere. The total surface area of the cone is equal to the total surface area of the hemisphere.
