7.G.B.4 Tutor Intake -- Area and Circumference of Circles

$\pi$ 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 ($d/C$).

The radius — the distance from the center of the circle to its edge.

The diameter — the distance across the circle through its center.

The circumference — the distance around the circle.

The rate at which the circle's area grows.
