Question
Find the volume of a sphere whose radius is $7 \ cm$
✓
Answer
$r = 7\ cm$
$∴$ Volume = ${4\over3}\pi r^3$
$={4\over3}\times{22\over7}\times(7)^3={4312\over3}\ cm^3=1437{1\over3}\ cm^3$
$∴$ Volume = ${4\over3}\pi r^3$
$={4\over3}\times{22\over7}\times(7)^3={4312\over3}\ cm^3=1437{1\over3}\ cm^3$
