What formulas would find the surface area of a right cylinder where h is the height and r is the radius and ba is the base area?

Answer 1

The surface area ( A ) of a right cylinder can be calculated using the formula ( A = 2\pi r(h + r) ), where ( h ) is the height and ( r ) is the radius. This formula combines the lateral surface area ( 2\pi rh ) and the area of the two circular bases ( 2\pi r^2 ). Alternatively, if you know the base area ( ba ), which is ( \pi r^2 ), you can express the surface area as ( A = 2ba + 2\pi rh ).
