3^2 : 14^2

OpenStudy (anonymous):

9 and 196

OpenStudy (anonymous):

Now do I do 9^2 : 196^2 ?

OpenStudy (anonymous):

what 3^2 and what's 14^2

OpenStudy (anonymous):

That would give me 81 and 38416 and that seems wrong b/c there is no answer choice for that

OpenStudy (anonymous):

3^2 = 9 14^2 = 196

OpenStudy (anonymous):

i did that part already

OpenStudy (anonymous):

that's for the area. for the volume its 3^3 : 14^3

OpenStudy (anonymous):

So B

27 and 2744
