# Right Cylinder Calc : Find A_B

The top and bottom surface area of a cylinder is called the base area. Both top and bottom base area of a cylinder is always the same. A right circular cylinder has two congruent circles as parallel bases and a lateral surface consisting of a rectangle. This simple online Right Cylinder Calculator is used to find A_B helps you to calculate the base area of the right circular cylinder using the radius of the base circle. The base area of cylinder is given as AB = Πr2.

The top and bottom surface area of a cylinder is called the base area. Both top and bottom base area of a cylinder is always the same. A right circular cylinder has two congruent circles as parallel bases and a lateral surface consisting of a rectangle. This simple online Right Cylinder Calculator is used to find A_B helps you to calculate the base area of the right circular cylinder using the radius of the base circle. The base area of cylinder is given as AB = Πr2.

#### Formula:

Base Area = π × r2 Where, r = Radius

### Example:

Find A_B of the right cylinder having radius as 8cm?

= π × 82
= 201.0619cm2
