Two Circles which are not congruent touch externally . The Sum of their areas is 130π and distance between their centres is 14 .F ind the radii of the circles . ........Guys plz answer i will mark as brainlist

Step-by-step explanation:
AREAS OF CIRCLES:-
πR^2+πr^2=130π
π(R^2+r^2)=130π
R^2+r^2=130π/π
R^2+r^2=130
R^2=130-r^2___________(1)
ALSO,
r^2=130-R^2____________(2)
PUTTING THE VALUE OF r^2 IN EQUESTION (1)......
R^2=130-r^2
R^2=130-130-R^2
R^2=r^2................ (3)
SO,
THE RADIUS OF BOTH THE CIRCLE IS GOING TO BE EQUAL....
THEREFORE,,,,
πR^2=130π
R^2=130
R=√130... .......
SO THE RADIUS OF BOTH THE CIRCLE IS √130.......... WHICH IS EQUAL TO 11.40......
