Question

A tank in the shape of a hemisphere has a diameter of 10 feet. If the liquid that fills the tank has a density of 84.6 pounds per cubic foot, what is the total weight of the liquid in the tank, to the nearest full pound?

Answer 1

22148 pounds

Explanation:

radius = half of diameter = 5.

Volume of hemisphere = (2/3) X π X r ³

= (2/3) X π X (5) ³ = (250/3)π

density = mass/volume, mass = density X volume

= 84.6 X (250/3)π

= 7050π

= 22148 pounds (to nearest full pound)
