B Correct answer
Explanation

The curved surface area of a cylinder is 2 * pi * r * h. Using r = 5.21, h = 23.41, and pi = 3.14: 2 * 3.14 * 5.21 * 23.41 = 6.28 * 121.9661 = 765.947108. Rounded to two decimal places, this is 765.95.

AI explanation

The curved surface area of a cylinder is calculated using the formula 2 times pi times radius times height. Substituting the given values gives 2 multiplied by 3.14 multiplied by 5.21 m multiplied by 23.41 m. Multiplying these values together gives a total curved surface area of 765.95 square meters.
