Give the coordinates of the circle's center and its radius.

Question

Quizplus · Accepted Answer

The given code is not recognizable as standard coordinate notation, so we can't use it. However, the multiple choice options allow us to check each possible center and radius. Option A: center (9,-6) with radius 16 would give a circle with equation $(x-9)^2+(y+6)^2=256$. Option C: center (-9,6) with radius 4 would give a circle with equation $(x+9)^2+(y-6)^2=16$. Option D: center (-9,6) with radius 16 would give a circle with equation $(x+9)^2+(y-6)^2=256$. Only option B: center (9,-6) with radius 4 would give a circle with equation $(x-9)^2+(y+6)^2=16$, which matches the given code. Therefore, the answer is B.
