# Curved surface area of cylinder calculator

### The steps to manually calculate the curved surface area of a cylinder:

- Identify the radius (r) and height (h) of the cylinder.
- Calculate the circumference of the base (C) using the formula:
**C = 2 * π * r**where π is a constant approximately equal to 3.14.

- Calculate the area of the base (B) using the formula:
**B = π * r^2** - Calculate the curved surface area of the cylinder (A) using the formula:
**A = C * h**where h is the height of the cylinder.

- Add the area of the base found in step 3 to the curved surface area found in step 4 to get the total surface area (T) of the cylinder:
**T = B + A** - Round the final result to the desired number of decimal places.

That’s it! You can now manually calculate the curved surface area of a cylinder.
