What is the radius, in inches, of a right circular cylinder if its lateral surface area is $3.5$ square inches and its volume is $3.5$ cubic inches?
Hint: set up a system of equations: \(2\pi r h=3.5\\ \pi r^2h=3.5\)
Divide the second equation by the first one:
\(\frac{\pi r^2h}{2\pi r h}=1\\ \)
then, cancel out like terms.
Can you take it from there?
