QuestionIdentify the false statement about the unit circle: A. $x^{2}+y^{2}=1$; B. radius 1 at origin; C. infinite integer points; D. $(a, b)$ if $a^{2}+b^{2}=1$.

Studdy Solution
Statement D A point $(a, b)$ lies on the graph of the unit circle if and only if $a^{2}+b^{2}=1$.
This is the definition of a point on the unit circle. So, statement D is true.
The statement that is not true is C There are infinitely many points that lie on the graph of the unit circle that have integer coordinates.
