The Formula is :
![v = (4)/(3) \pi {r}^(3)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/wtnwmw48nsxl5ixik787559s4fn7inkl45.png)
V= volume
R = Radius
![\pi = 3.14159265359](https://img.qammunity.org/2019/formulas/mathematics/middle-school/fqkbaf6vjaqlo19zn3rtruwdhv703hhdcr.png)
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](https://img.qammunity.org/2019/formulas/mathematics/middle-school/xw28qy5xkpglwifgecj3u77fgotssteq0n.png)
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
