Answer :
The possible change in volume (in mm3) resulting from the error in measuring the radius is 32. 06 mm³
How to determine the volume
The formula for volume of a sphere is expressed by;
Volume = 4/3 πr³
Where;
- r is the radius of the sphere
- pi takes the value 3.14
From the information given, we have that the measured radius is 5 mm, with a possible measurement error of 0.1 mm
Then, radius a = 5mm
Radius b = 5 + 0. 1 = 5. 01mm
Now, substitute the values into the formula
Volume, v = 4/ 3 (3.14)(5)³
expand the bracket
Volume, v = 4/ 3 (392.5)
Volume, v = 523. 3 mm³
For radius of 5.01mm
Volume = 4/ 3 (3.14)(5.1)³
expand the bracket
Volume = 4/3 (416.52)
Volume = 555. 4 mm³
The change in volume = 555. 4 - 523. 3 = 32. 06 mm³
Hence, the change in volume is 32. 06 mm³
