Question

Find the depth of a cylindrical water tank is 1078m cube. and the radius of the base is 7m?

Answer 1

$\bf{Given : }$

Radius = 7m

Volume of cylinderical tank = 1078 m^3 .

$\bf{Solution:}$

We know that

$\bf{Volume\:of \:cylinder \:=\:{\pi}\:{r}^{2}}}h$

$1078 = \frac{22}{7} \times 7 {}^{2} \times h$

$1078 = \frac{22}{7} \times 7 \times 7 \times h$

$1078 = 22 \times 7 \times h$

$\frac{1078}{22 \times 7} = h$

Dividing by 11.

$\frac{98}{2 \times 7} = h$

$\frac{98}{14} = h$

7 = h

$\bf{So,\:Height\: =\:7\:m }$
