不好意思 因為圖表題貼不出來我把它貼在附件哩! 懇請戰友 過目一下 In the figure above, a square is inscribed in a circle.If the area of the square region is 16, what is the area of the circular region?
(A)2π
(B)4π
(C)6π
(D)12π
(E)16π
我的思路是把她對切再對切可得到2^2加2^2=X^2
所以x等於根號8也就是半徑得到面積8 拍
可是裡面沒有= =
In the figure above, equilateral triangle ABC is inscribed in the circle.If the length of arc ABC is 24, what is the approximate diameter of the circle?
(A) 5
(B) 8
(C) 11
(D) 15
(E) 19
