1. Understand the Formula:
The curved surface area of a cylinder is given by:
* CSA = 2πrh
Where:
* CSA is the curved surface area
* π is a mathematical constant approximately equal to 3.14159
* r is the radius of the cylinder (half the diameter)
* h is the height (or length) of the cylinder
2. Calculate the Radius:
* Diameter = 8 cm
* Radius (r) = Diameter / 2 = 8 cm / 2 = 4 cm
3. Plug in the Values:
* CSA = 2 * 3.14159 * 4 cm * 12 cm
4. Calculate the Curved Surface Area:
* CSA = 301.5928 cm²
Therefore, the curved surface area of the cylinder is approximately 301.59 cm².
