B Correct answer
Explanation

Surface area of a cylinder = 2*pi*r*(r+h). Area = 2 * (22/7) * 7 * (7 + 11) = 2 * 22 * 18 = 44 * 18 = 792 cm^2.

AI explanation

A cold drink can is shaped like a closed cylinder, and its total surface area is calculated using the formula 2 * pi * r * (r + h). Substituting the given values of radius as 7 cm and height as 11 cm, and using pi as 22/7, the calculation becomes 2 * (22/7) * 7 * (7 + 11) = 44 * 18 = 792 cm2. The surface area of the cold drink can is 792 cm2.
