Question

find the error in the measurement of volume of sphere if error in the measurement of radius is 1%

Answer 1

Volume of sphere we have is 4/3πr^3

so for measuring error in the sphere 4/3 is a constant which cannot have any error.

Radius is variable where we need to bring the cube in front like this

3 ( r ) = 3 * 1% = 3% .

Hope it helps!
