A spherical soap bubble with radius of 2 cm lands on a flat surface. Its shape changes to that of a hemisphere. Assuming that none of the air inside the bubble escapes, determine the radius of the hemisphere.

Calculate the volume of air inside the original bubble. Since no air escaped, the hemisphere still contains that much air. Use the formula for volume of a hemisphere to find the radius.

floor section Of Sphere = 4 Pi r^2 quantity of spere = 4/3 Pi r^3 a) radius doubled - floor section will exchange into sixteen time than until now quantity would be 8 cases greater. b)radius tripled - floor section will exchange into 36 cases of until now. and quantity would be 27 cases greater. b) multipled with the aid of n . floor section would be n^2 cases greater and quantity would be n^three times greater
