You can put this solution on YOUR website!
[ area A ] / [ area B ] = +pi%2Ar%5BA%5D%5E2+ / +pi%2Ar%5BB%5D%5E2+
-------------------------------------------------
[ area A ] / [ area B ] = +r%5BA%5D%5E2+%2F+r%5BB%5D%5E2+
----------------------------------------
[ area A ] / [ area B ] = +5%5E2+%2F+6%5E2+
-----------------------------------
[ area A ] / [ area B ] = +25%2F36+
-------------------------------
The answer is B.
