Having a major rectal cranial inversion and can't figure this out although it should be very simple?
I know the volume and length of a cylinder, how do I figure out the radius of that cylinder. Length of cylinder is 1.3 miles and volume is 3800 cubic feet. Thank you for your help.

First of all, 1.3 miles = 6 864 feet. Now, we must do a little algebra. We shall solve the volume of a cylinder for radius.
V=πr²h
V/πh=r²
r=sqrt(V/πh).
V=3800 ft³
π=3.14159265
h=6864 ft
sqrt(V/πh)=0.41978626476509673741162227011684 ft
Therefore, the radius is approx. 0.42 ft, or 5.0 inches.
I make no claims to the correctness of this advice. Use your own judgement accordingly.
