Let the variable line \( a x+b y+c=0 \), where \( a, b, c \) are in arithmetic progression be normal to a family of circles. If \( r \) be the radius of the circle of the family which intersects the circle \( x^{2}+y^{2}-4 x-4 y-1=0 \) orthogonally, then find the value of \( r^{2} \).https://bit.ly/YTAI_PWAP https://www.pw.live
