What's the surface area ratio & the volume ratio??

please help me ASAP!!

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

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
