The answer is 3 cm.
Circle A's diameter is 27, right? However, circle A is 3 times the value of the area of B. Because of that, you need to do 27/3, the inverse, in order to get the diameter of circle B.
Next, because radius is half of the diameter, you do 9 divided by 3 or 9 times 1/2.

Apply lg on both sides.
lg7^x^2 = lg9^x
Bring the power forward.
x^2lg7 = xlg9
x^2/x = lg9/lg7
x = lg9/lg7 = 1.13
