i've been stuck on this for a while so if you know the answer or know how to figure it out then please attch the website...

Thank You SOOOOO much!!!

Answer 1

Circumference

= (diameter)(pi)

= 22pi

= 22(3.1415)

= 69.11503838...

To the nearest foot = 69 ft.

Answer 2

Okay, to get the circumference from a diameter you multiply it by pi.

Pi equals 3.1415926

So 22 times pi=69.1150372.

To the nearest tenth it would be, 69.1.
