பயன்படுத்தப்பட்ட வாய்ப்பாடு :

கோளத்தின் கனஅளவு =\(\frac{4}{3}πr³\)

கணக்கீடு:

ஆரம் பாதியாக உள்ளது, அதாவது, புதிய ஆரம் =\(\frac{r}{2}\)

இப்போது, புதிய கன அளவு

\((\frac{4}{3})π(\frac{r}{2})³\)

\((\frac{4}{3})(πr³)(\frac{1}{8})\)

\(\frac{Volume}{8}\)

எனவே, கன அளவு \(\frac{1}{8}\)மடங்குகளாக மாறும்.
