CIRCLE, CIRCLE...Geometry Level pending
There are three circles, A, B and C.. If the sum of the diameter of circle A and B is to be 23 units, circle B and C to be 34 units and circle A and C to be 47 units, find the sum of the diameter of the smallest circle that can lie tangent internally to the three circles and the radius of the largest circle that can circumscribe the three circle.. Round your answers to four decimal places..
Hope you enjoy my problems! :D
