A hemispherical tank is filled with water and has a diameter of 14 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank,
to the nearest pound?

Step-by-step explanation:

Given that,

The diameter of a hemispherical tank= 14 feet

Radius, r = 7 feet

water

Water weighs 62.4 pounds per cubic foot.

We need to find the total weight of the water in a full tank to the nearest pound.

The volume of the hemisphere is given by :

If water weighs 62.4 pounds per cubic foot, it means

So, the total weight of the water is .

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

its very big question plz make it small
