In order to fight the drought, Xiaoping's family dug a cylindrical reservoir with a bottom radius of 5m and a depth of 2m, and coated the inner wall and bottom of the pond with cement to prevent water leakage. After a heavy rain, Xiaoping walked around the edge of the pool and measured the water depth in the pool to be 1.2m. Based on the above information, pose a mathematical problem and answer it.
为了抗旱，小平家挖了一个底面半径5m、深2m的圆柱形蓄水池，并且用水泥涂抹水池的内壁与底部，防止漏水．一场暴雨过后，小平沿水池边缘走了一圈，并测得池中水深1.2m．根据以上信息，提出一个数学问题并解答．
