A cylindrical tank has a capacity of 4774 \(m^3\). If the radius of the  base is 7 m, what is the depth?

Solution / समाधान

Volume of a cylinder:

$V = \pi r^2 h$

Given:

Volume $= 4774 , m^3$

Radius $r = 7$ m

$\pi = \frac{22}{7}$

Substituting the values:

$4774 = \frac{22}{7} \times 7 \times 7 \times h$

$4774 = 154h$

$h = \frac{4774}{154}$

$h = 31$

Depth of the tank / टंकी की गहराई:

👉 31 m
