Question

The equation for the circle is (x-2)^2 + (y-1)^2 = 4 True or False???

Answer 1

True because the center is (2,1) and radius is 2

Answer 2

The equation for a circle is:

(x - h)^2 + (y - k)^2 = r^2

h = the x value of the center

k = the y value of the center

r = length of radius

In this case the center is (2, 1) and the radius is 2 units, meaning:

h = 2

k = 1

r = 2

The equation for this circle is:

(x - 2)^2 + (y - 1) = 4

This matches the equation given in the question so the answer is True!

Hope this helped!
