How do you calculate the square footage on the surface of a cylinder if you know the diameter and length?

Thank you Ms Sue.
You're welcome.
To calculate the surface area of a cylinder, you need to find the sum of the areas of the two circular bases and the lateral surface area. The formula to calculate the surface area of a cylinder is:
Surface Area = 2πr² + 2πrh
Where:
- π is a mathematical constant approximately equal to 3.14159
- r is the radius of the circular base, which is half the diameter (since diameter = 2 * radius)
- h is the height or length of the cylinder
To calculate the radius (r) from the diameter (d):
- Divide the diameter by 2, since the radius is half of the diameter. So, r = d/2.
Once you have the radius, you can substitute the values of r and h into the surface area formula to calculate the square footage on the surface of the cylinder.
