Circle A has a center at #(2 ,5 )# and a radius of #2 #. Circle B has a center at #(4 ,-1 )# and a radius of #6 #. Do the circles overlap? If not, what is the smallest distance between them?
If you make a right angled triangle between the two centres, using the line that joins them as the hypotenuse. The height of the triangle is 6 and the base is 2. Using Pythagoras the hypotenuse would be
