Answer 1

$\huge\red{\mid{\fbox{\tt{ANSWER}}\mid}}$

Capacity of storing water=Volume of cylindrical

tank

2156 kl=2156 x 1000000 cm^3 Volume of cylinder=2156*10^6 pi r^2h. =2156×10^6

Here,

h=height of tank

r=diameter-2=14-2=7m3D700cm.

3.14x(700)^2xh=2156*10^6

h=2156x10^6=3.14x49x10^4 =2156x10^6x10^-4-3.14x49

=2156x10^2=153.86

= 21560015386

=1401.274 cm h=14.012m

Therefore height Of cylindrical tank is '14.012m.
