Well, to find the circumference of a circle, we can use the formula C=2r. So just plug in 3.5 into the formula. C=23.5. Multiply and we get C=21.99. which is about 22 So our answer would be C. 22 feet. Hope I helped!
Ordered pairs that equate to a function would not have two separate points with the same x-value. In other words, every x-value must be associated with only one y-value.
