The radius of the cylinder is 14 meters (diameter of 28 meters divided by 2). Using the formula for the volume of a cylinder, V = πr²h, where π is approximately 22/7, r = 14 meters, and h = 4.5 meters, we get:
V = (22/7) x 14² x 4.5
V = (22/7) x 196 x 4.5
V = 11,088 cubic meters (rounded to the nearest whole number)
Therefore, the volume of the cylinder is approximately 11,088 cubic meters. The answer is (A) 11,088 cubic meters.
