The Formula is :


v = (4)/(3) \pi {r}^(3)

V= volume
R = Radius

\pi = 3.14159265359
Or just simply: 3.14

Radius- length to the middle of the circle.
***Do not be confused with diameter. Diameter is from one end to the sphere the other end of the sphere. If you DO get a diameter, just simply split it in half.

So if the radius was 2 you would do:
2×2×2
=8
Then you would multiply 8 by 4:
8×4
=32
Then you would divide by 3
32÷3
=10.6666666667 or rounded to 10.67

Your exact answer would be:

10.67\pi
Or yo find your approximate answer:
10.67×3.14159265359
= 33.52079361

or 10.67×3.14
=33.5048

It depends on your teacher, if he or she wants you to do it one way (3.14) or the other (exact pi number)

I hope this helps. I was bored so I went extra lol
