The community has a centralized reservoir which is conical with a radius of 7 m and height 20 m. If the reservoir is half filled, how long, to the nearest day, will the water last? [Take π=22/7)

What this sentence really means - "the reservoir is half filled" ?

Does it means "half filled by the height" or "half filled by the volume" ?


Why such carelessness in the wording?


If you think that it is a Math problem, then you make a GREAT mistake.
