Question

the volume of a mud taken out on digging a cylindrical tank is 1540metercube. find the depth of the tank if the diameter of the base is 7m?

Answer 1

hi..


volume of mud = volume of tank = 1540m^3

r = 7/2

$\pi \: {r}^{2} h = 1540$

$\frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} \times h = 1540$

$\frac{77}{2} \times h = 1540$

$h = 1540 \times \frac{2}{77}$

$\bold{h = 440m}$
