Answer:
They used 3.14 for pi:


Step-by-step explanation:
is the volume of a sphere with radius r.
I think that is the diameter given in the picture.
The radius is half the diameter.

Plug in this gives you:

It is 6 units because you find the absolute value of the two different coordinates, in this case it is 4 and -2. Since they belong in different quadrants (one x or y value is positive and the other is negative) you add them. If they are both in the same quadrant, you subtract them.
8.8 squared + 9.5 squared = square root 12.94 rounded 12.1
