Please help me solve this problem: Two circles have their centers at (2, 4) and (-14, 2) and they intersect at the point (-2, 7). What is the radius of each circle?
\n" ); document.write( "-------------
\n" ); document.write( "The radius is the distance from the center to the point (-2,7).
\n" ); document.write( "From (2,4) to (-2,7):
\n" ); document.write( " $\"d+=+sqrt%28diffy%5E2+%2B+diffx%5E2%29+=+sqrt%284%5E2+%2B+3%5E2%29\"$
\n" ); document.write( "r = 5
\n" ); document.write( "------------
