"The distance across a circle through the center is called the diameter"
"The diameter of a circle is twice as long as the radius"

Circumference
The circumference of a circle is found using this formula:
$C= \pi * d \ \ \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ \ \ C=2\pi *r$

Area

The area of a circle is found using this formula:

$A= \pi * r^(2)$

******************************************
Diameter = 12m
radius = 6m

Circumference

$C=\pi*d \\C=\pi*12 \\C=12\pi \\C=37.699 \\C=37.70$

Area

$A=\pi*r^2 \\A=\pi*(6)^2 \\A=\pi*36 \\A=36\pi \\A=113.097 \\A=113.10$
