A tank in the shape of a hemisphere has a radius of 7 feet. if the liquid that fills the tank has a density of 93 pounds per cub
professor190 [17]

The total weight of the liquid that filled the hemispheric tank to the nearest full pounds is 66775 pounds.

<h3>What is the volume of an hemisphere?</h3>

An hemisphere is half of a sphere. Therefore,

volume = 2 / 3 πr³

where,

  • r = radius

Therefore,

r = 7 feet

volume = 2 / 3 × 3.14 × 7³

volume = 2 / 3 × 3.14 × 343

volume = 2154.04 / 3

volume = 718.013333333

volume = 718.013

Therefore,

density = mass / volume

93 =  mass / 718.013

mass = 718.013 × 93

mass = 66775.24

mass ≈ 66775 pounds

zmey [24]
(((6x-(2*(x3)))+10x)+(2*(x3)))+7x4 \\ \\ Then \ we \ simplify \ it \ down \ more. \\ \\   (((6x-(2*(x^3)))+10x)+2x^3)+7x^4 \\ \\ then \ we \ would \ then \ pull \ out \ the \ like \ factors . . . . \\ \\  7x^4 + 16x  =   x * (7x^3 + 16) \\ \\

Your final answer: \boxed{\bf{  x *(7x^3 + 16)}}
