Question

a cylindrical water tank has a capacity of 2156kl and diameter of its base 14m.find the depth of the tank.

Answer 1

Capacity of storing water=Volume of cylindrical tank

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

Here,
h=height of tank
r=diameter÷2=14÷2=7m=700cm. ...(1m=100cm

3.14×(700)^2×h=2156×10^6
h=2156×10^6÷3.14×49×10^4
=2156×10^6×10^-4÷3.14×49
=2156×10^2÷153.86
=215600÷153.86
=1401.274 cm
h=14.012m

Therefore height Of cylindrical tank is '14.012m'.
