Answer:
- Percentage error in volume of sphere = 6
Explanation:
Given,
- Error in the measurement of radius (R) is 2
To find,
- Percentage error in the determination of volume (V) of sphere= ?
Solution,
- Given that percentage error in the measurement of radius is 2 therefore, relative error will be 2/100 ; that is
Since, volume of sphere is given by
so,
Since, 4/3 and π are constant so, they will not have any effect in the error determination of volume hence, error in volume is dependent on r³ only.
- Using rule
[ The relative error in a quantity raised to a power k is given by k times the relative error in the individual quantity ]
therefore,
so, We have relative error in the volume in sphere
Hence, Percentage error in the volume would be
Hence,
