Persamaan lingkaran yang berpusat di A(3,2) dan berjari - jari 5 adalah ....

(x3)2+(y2)2=5\left(x-3\right)^2+\left(y-2\right)^2=5

(x3)2+(y2)2=25\left(x-3\right)^2+\left(y-2\right)^2=25

(x+3)2+(y2)2=25\left(x+3\right)^2+\left(y-2\right)^2=25

(x+3)2+(y+2)2=25\left(x+3\right)^2+\left(y+2\right)^2=25

(x3)2+(y+2)2=5\left(x-3\right)^2+\left(y+2\right)^2=5
