#### Answer

644 ft and 1559ft

#### Work Step by Step

$R=\frac{v^{2}}{g(f + tan\theta)}$
A larger value of $\theta$ will lead to larger value of $\tan\theta$. As $\tan\theta$ increases, then the ratio R will decrease. Thus radius can be smaller anf curve sharper if $\theta$ will increase
$R_1 =\frac{66^{2}}{32.2(0.14 + tan 4^{\circ})} = 644ft$ $\lt703ft$
$R_2 =\frac{102.67^{2}}{32.2(0.14 + tan 4^{\circ})} = 1559ft$ $\lt1701ft$
