Step-by-step explanation:
Volumes of two spheres A and B = 648 cm³ and 1029 cm³
Things to remember:
1). Scale factor of two objects = [
and
are the radii of two circles]
2). Area scale factor =
3). Volume scale factor =
Volume scale factor Or Volume ratio =
Therefore, scale factor =
≈ 6 : 7
Area scale factor Or area ratio =
=
≈ 36 : 49
Volume scale factor or Volume ratio =
=
≈ 216 : 343
