Help! i give medals
The volumes of two cylinders are 2197pi and 8000pi
Find the following:

Answer 1

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

Answer 2

\[v=\pi r^{2}h,V=\pi R ^{2}H,a=2 \pi r h ,A=2 \pi R H,\frac{ v }{a }=\frac{ \pi r ^{2} h}{ 2 \pi r h }=\frac{ r }{ 2 }\]
\[similarly \frac{ V }{A }=\frac{ R }{2 }\]
Now you can calculate whatever you want.
