The Formula is :
[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]
V= volume
R = Radius
[tex]\pi = 3.14159265359[/tex]
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:
[tex]10.67\pi[/tex]
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
