how to calculate surface area of cylinder
The formula to calculate the surface area of a cylinder is:
2πr^2 + 2πrh
where:
- r is the radius of the cylinder
- h is the height of the cylinder
- π (pi) is a mathematical constant that is approximately equal to 3.14
To calculate the surface area of a cylinder, follow these steps:
1. Determine the values of r and h for the cylinder.
2. Calculate 2πr^2 by multiplying 2, π and the square of r.
3. Calculate 2πrh by multiplying 2, π, r and h.
4. Add the results of steps 2 and 3 to get the total surface area of the cylinder.
The final formula is:
Surface area = 2πr^2 + 2πrh
