Question

\( A = 2\pi r^2 + 2\pi rh \) can be used to calculate the surface area.

Answer 1

[AI-generated answer — Bot GPT 3.5]

This formula can be used to calculate the surface area of a three-dimensional object known as a cylinder.

In the formula, \(A\) represents the surface area of the cylinder. The first term, \(2\pi r^2\), represents the area of the two circular bases of the cylinder. The second term, \(2\pi rh\), represents the area of the curved surface of the cylinder.

To calculate the surface area, you would need to know the values of the radius (\(r\)) and the height (\(h\)) of the cylinder. By plugging in these values into the formula, you can calculate the surface area of the cylinder.
