Question

A hemispherical water tank has an inside diameter of 8 feet. If water has a density of 62.4 pounds per cubic foot, what is the weight of the water in a full tank, to the nearest pound?

Answer 1

Answer:

weight of water= 8360 pounds

Step-by-step explanation:

volume of hemispherical water tank= 2πr³/3

2×3.14×4⁴/3= 133.97 feet³

weight of water in full tank = volume× density

= 133.97 × 62.4

= 8360 pounds
