Circumference of the circle is found using the formula 2πr. Since you have the diameter you can divide it by 2 to find the radius.

7/2 = 3.5

So the radius is 3.5. Now the circumference.

2(3.14)(3.5) = 21.98 ft

So the circumference is 21.98 ft

Hope this helps :)

The circumference of a circle is either [tex]2 \pi r[/tex] or [tex] \pi d[/tex]. In your case it's the latter. [tex] \pi [/tex], or 'pi', is equal to 3.14.

3.14 * 7 = 21.98.

Thus the circumference of a circle where the diameter of said circle is 7, is 21.98 [ft].
