Question

A circle has its center at (1, 4) and a radius of 2 units. What is the equation of the circle?

A.(x + 2)2 + (y + 4)2 = 2
B. (x - 1)2 + (y - 4)2 = 4
C. (x + 1)2 + (y - 4)2 = 4
D. (x - 1)2 + (y - 4)2 = 2

Answer 1

Equation of a circle is. (X-x0)^2 + (y-y0)^2 = r^2

(X0 , y0) is center of circle and r is radius

Answer 2

Im kind of confused whats the answer? @Gebooors

Answer 3

You have to put (1,4) and r = 2 in the equation..

Answer 4

Ohhhhh thank you!
