D Correct answer
Explanation

Area of circle P = pi * r^2 = pi * 6^2 = 36pi. Area of circle Q = 81pi. Total area = 36pi + 81pi = 117pi.

AI explanation

The area of circle P is pi r squared, which equals 6 squared times pi, yielding 36 pi square cm. The area of circle Q is given as 81 pi square cm. Adding these two areas together gives 36 pi plus 81 pi, resulting in a total area of 117 pi square cm.
