Question

Rain water, which falls on a flat rectangular surface of length $6m$ and breadth $4m$ is transferred into a cylindrical vessel of internal radius $20cm$. What will be the height of water in the cylindrical vessel if a rainfall of $1cm$ has fallen? (Use $\pi =\frac{22}{7}$)

Answer 1

$L\times B\times H=\pi r^{2}h$

$6\times 4\times 0.01=\pi {0.2}^{2}h$

$h=1.9098m=190.98cm$
