Step-by-step explanation:

Actually, it can be solved without solving the differential equation. You just put the given numbers into the given equation.

dy/dx = x/y

For (x, y) = (-2, -4), dy/dx = (-2)/(-4) = 1/2

For (x, y) = (0, 1), dy/dx = 0/1 = 0

For (x, y) = (1, 2), dy/dx = 1/2

The volume of Earth is .

To solve, you must remember that to find the area of a circle, (includes volume since circle volume and area is same) you must do A=πr².

So, A=π3958.75²

How did we get 3958.75? Well, to find the area, you must multiply r by r (radius).

So, 3958.75² is 15671701.5625.
