Calculation of approximate value

The diameter of a soap bubble is 3.5 cm. In blowing it further, if 36960 ergs of work is done then calculate the approximate value of final radius of the soap bubble in cm if surface tension of soap solution is 40 dynes/cm.

Approximate value of GFR

A person takes 6.1 g of an anta-acid tablet comprising bicarbonate ion at 20.8%. The volume of CO_(2) evolved at (1 atm and 25^(@)C ) in the stomach (on neutralisation) multipled by a factor of '10' will be x L . Calculate the approximate (integer) value of x .

The difference between exact value and approximated value is "_______" .
