Approximate area rounded to the hundredth?! That's some fine approximating.

A = πr² = πd²/4 = π*121/4 = 95.03in²

A = pi r^2 where 'r' the radius is half the diameter . Hence r = 11/2 = 5.5 Hence A = 3.1415192... x 5.5^2 A = 95.033177771091245463494962344205 sq.ins. A = 95.03 sq. ins. ( Nearest hundredth).

Area = π(d/2)^2 = π(11/2)^2 = π(5.5)^2 = 93.03 in^2

Okay done, now what is your question that you can't answer. Area = pi*r^2.
