a spherical storage tank has a diameter of 24 ft and is full of water. how many delivery trucks with a cylindrical tanks measuring 4 ft in diameter and 10 ft long can be completely filled from the storage tank?

Respuesta :

Diameter of the spherical storage tank = 24 ft

So, radius of the tank = [tex]\frac{24}{2}=12[/tex] ft

Volume of the spherical tank = 4/3 * PI * r³

= [tex]\frac{4}{3}\times3.14\times12\times12\times12[/tex]

= 7234.56 cubic feet

Diameter of cylindrical tank = 4 ft

So, radius = [tex]\frac{4}{2}=2[/tex] ft

Height of cylindrical tank = 10 ft

Volume of cylindrical tank = PI * r² * h

= [tex]3.14\times2\times2\times10=125.60[/tex] cubic feet

So, the number of cylindrical tanks that can be filled from the spherical tank are =

[tex]\frac{7234.56}{125.60}=57.6[/tex]

Hence, 57 cylindrical tanks can be completely filled from the big spherical tank.
