Question

A circle has its center at (1, 4) and a radius of 2 units. What is the equation of the circle? (1 point)
Select one:
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 circle: (x-h)^2 + (y-k)^2 = r^2 when r = radius and (h, k) is the center
so if the center is (1, 4) and radius is 2
plug it into the equation and see what you get :)

Answer 2

so it would be answer b right?

Answer 3

yep :)

Answer 4

thank you

Answer 5

your welcome :D
