Master Calculating Surface Area Of A Cylinder With Easy Formulas And Critical Tips

Surface area of a Cylinder

Volume of Triangle Prism= (area of triangular base)x(height of prism)

The surface area of a cylinder is the total area of all its curved and flat surfaces. It can be found by adding the area of the two circular bases to the lateral area of the cylinder.

To calculate the lateral area of a cylinder, we can use the formula LA = 2πrh, where r is the radius and h is the height of the cylinder. The lateral area represents the curved surface area that connects the two circular bases.

To find the area of one circular base, we can use the formula A = πr², where r is the radius of the base. Since a cylinder has two circular bases, we need to multiply the area of one base by 2 to get the total area of the bases.

Therefore, the formula for the surface area of a cylinder is:

SA = 2πr² + 2πrh

where r is the radius and h is the height of the cylinder.

It’s important to note that the units for the radius and height must be the same. If, for example, the radius is given in centimeters and the height is given in meters, we must convert one of the values so that they are both in the same unit.
