Answer:
Height = 80 cm
Explanation:
Base area = 750 cm
Volume of water = 30,000 cm³
Since the tank is half-filled with water, it's volume is twice the amount of water.
Volume = 30,000 * 2 = 60,000 cm³
To find the height of tank;
Mathematically, the volume of a cylinder is given by the formula;
Volume = base area * height
Substituting into the formula, we have;
60,000 = 750 * height
Height = 60000/750
<em>Height = 80 cm</em>
