9ft? to get the circumference, we multiply the diameter to pi, so all we need to do is divide 28 ÷ π, and round.
9ft because to get circumference you multiply by π (pi or 3.14) so to get circumference you just do it the other way around like:
28 ➗π (3.14) = 8.91710...
Which rounds to 9. So, the diameter is 9ft. I hope I helped and just message me if you need anything else!
