Answer:
The radii of the circles are 12 cm and 7cm.
Step-by-step explanation:
Let the radii of the circles be 
Given:
Sum of circumference of two circles= 38π cm
Formula for circumference of a circle with radius r = 2πr
------------1
Sum of areas of two circles= 193π cm²
Area of circle with radius r = πr²
-------2
Substituting r2 = 19 - r1 in equation 2 we get:

Then r2 = 19 - r1
