 By trial it was found that the value of d\ 

 which very nearly satisfied this equation 

 was d 1 = 10993 cm. Having found the in- 

 ternal diameter of the bubble, it was com- 

 paratively simple to calculate the surface 

 area. This is made up of the top hemi- 

 spherical area + cylindrical area 4- base area:
