C Correct answer
Explanation

Volume of a cylinder = pi * r^2 * h. V = 3.14159 * 5^2 * 10 = 3.14159 * 25 * 10 = 785.39 m^3. Rounded to the nearest whole number, this is 785 m^3.

AI explanation

Using the formula for the volume of a cylinder, V = pi * r^2 * h, we substitute the base radius of 5 m and height of 10 m. This gives V = 3.14 * 5 * 5 * 10 = 785 cubic m. The result is 785 m3.
