Answer:
The appropriate answer will be "Y = 157.09 N/m³".
Explanation:
The given values are:
Diameter
= 7.5 ft
= 0.3048 meter
Height
= 20ft
= 6.096
Weight density
= 45.93 lb/ft³
= 16.0184634 kg/m³
Acceleration
= 9.807 m/s2
As we know,
The specified density of weight can be expressed as:
⇒ Specific weight = density × acceleration
i.e.,
⇒

On substituting the estimated values in the above expression, we get
⇒
