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