Easy -2.0 This is a 1-mark multiple choice question requiring only recognition that r²=9 means r=3, then applying A=πr²=9π. It involves direct recall of the circle equation form and area formula with no problem-solving, making it significantly easier than average A-level questions.
A circle has equation \((x - 4)^2 + (y + 4)^2 = 9\)
What is the area of the circle?
Circle your answer.
