Answer:
- 4.77 %
Explanation:
We know that the volume V for a sphere of radius r is
If we got an uncertainty the formula for the uncertainty of V is:
We can calculate this uncertainty, first we obtain the derivative:
And using it in the formula:
The relative uncertainty is:
Using the values for the problem:
This is, a percent uncertainty of 4.77 %
