CastleRookA] Volume ratio is given by: (volume of large sphere)/(volume of small sphere) volume of large sphere=686 yd³ volume of small sphere=250 yd³ thus volume ratio will be: 686/250 =343/125 b] Linear scale factor=∛(volume ratio) but volume ratio=343/125 hence: scale factor=∛(343/125)=∛(7³/5³)=7/5 c] area ratio=(scale factor)² but scale factor=7/5 thus area ratio=(7/5)²=49/25
