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

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
