Circles do not overlap. Smallest distance #d_b=5sqrt2-7=0.071067" "#unit

Explanation:

Compute the distance #d# between centers using distance formula

#d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)#

#d=sqrt((2--3)^2+(8-3)^2)#

#d=5sqrt2#

Add the measurements of the radii

#r_t=r_1+r_2=4+3=7#

Distance #d_b# between circles

#d_b=d-r_t=5sqrt2-7=0.071067" "#
