Answer

$0.420\rm{ft}$

Work Step by Step

The length is $1.3$ miles which is the same as $1.3\times5280=6864$ feet. The volume of the cylinder is $3800 \rm{ft}^3=\pi r^2h$. The height is 6864 and therefore $3800=6864\pi r^2$. Solving for $r$ we get $r=\sqrt{\frac{3800}{6864\pi}}\approx0.420\rm{ft}$
