Question

In hospital used water is colected in a cylinder tank of diameter 2 m and height 5 m. After recycling., this water is used to irrigate a park of hospital whose length is 25 m and breadth is 20 m . If tank is filled completely then what will be the height of standing water used for irrigating

Answer 1

$\begin{array}{c}Volumeofwaterincylinder=volumeofwaters\tan dinginpark\\ \pi r^{2}h=a\times b\times H\\ \pi \times 1^2\times 5=25\times 20\times H\\ H=\pi /{100}^m\\ \left[H=3.14cm\right]\end{array}$
