Help! I give medals Ratios will be below..... The volumes of two similar cylinders are 2197pi cubed and 8000pi cubed find the following ratios:

OpenStudy (anonymous):

\[\frac{ r1 }{ r2 }=\frac{ h1 }{ h2 }=\frac{ a }{ b}\] \[\frac{ Area I }{ Area II }=\frac{ a ^{2} }{ b ^{2} }\]

OpenStudy (anonymous):

the scale factor of similarity will be the cube root of the ratio...8000pi/2197pi...what is the question asking?...i dont understand what you are looking for.

OpenStudy (anonymous):

the question is asking for the ratios above and they give me what I gave you above

OpenStudy (anonymous):

are you looking to solve for a and b then?...if so then 8000^(1/3) = 20 and 2197^(1/3) = 13 a=20 and b=13

OpenStudy (anonymous):

Ok so the would I just square that to get the bottom one

OpenStudy (anonymous):

yup :-)
