A water storage tank is in the shape of a hemisphere (half a sphere). If the radius is 20 ft, approximate the volume of the t

otez555 [7]

Answer:

The approximate volume of the tank is $V=16,747\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a hemisphere (water storage tank) is equal to

$V=\frac{4}{6}\pi r^{3}$

we have

$r=20\ ft$

assume

$\pi =3.14$

substitute

$V=\frac{4}{6}(3.14)(20)^{3}$

$V=16,747\ ft^{3}$
