#"what we have to do here is compare the distance (d)"#
#"between the centres with the sum of the radii"#
#• " if sum of radii"> d" then circles overlap"#
#• " if sum of radii"< d" then no overlap"#
#"to find the radii use area (A) of circle formula"#
#•color(white)(x)A=pir^2#
#"circle A "to pir^2=16pirArrr=4#
#"circle B "to pir^2=3pirArrr=sqrt3#
#"calculate d using the "color(blue)"distance formula"#
#•color(white)(x)d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)#
#"let "(x_1,y_1)=(2,5)" and "(x_2,y_2)=(8,1)#
#d=sqrt((8-2)^2+(1-5)^2)=sqrt(36+16)=sqrt52~~7.211#
#"sum of radii "=4+sqrt3~~5.732#
#"since sum of radii"< d" then no overlap"#
#"minimum distance "=d-" sum of radii"#
#color(white)(xxxxxxxxxxxxxx)=7.211-5.732=1.479#
