Question

Which of the following is the equation of the circle with center (4, 0) and r =√5.
Choose one answer.
a. x^2 + (y - 4)^2 = 5
b. x^2 + (y + 4)^2 =√5
c. (x + 4)^2 + y2 =√5
d. (x-4)^2+y^2=5

Answer 1

\[(x-C_x)^2+(y-C_y)^2=r^2\]

Answer 2

where Cx and Cy are the center parts

Answer 3

(x-a)^2+(y-b)^2=r^2 where (a,b) is the centre of the circle and r is the radius
