Pi ( $\pi$ ) is defined as the ratio of a circle's circumference to
its diameter ( $\pi = C/d$ ). Which statement about $\pi$ is TRUE?

$\pi$ is an exact value equal to 3.14159..., a number that never ends or repeats; 3.14 is only an approximation of it.

$\pi$ equals exactly 3.14, with no digits after the hundredths place.

$\pi$ changes value depending on how large the circle is.

$\pi$ is defined as the diameter divided by the circumference ( $d/C$ ).
