The circumference of an 18-foot circular swimming pool is: 56.55 feet.
The circumference of a 27-foot diameter circle is about 84.82 feet. (diameter x Pi = circumference).
If you are asking about a 27' circumference pool, then the answer is 27'
About 62 times. This assumes you mean the pool is 27 feet across. If you mean the circumference of the pool is 27 feet, you would have to walk around it about 196 times.
The circumference of a circle with a 27 foot diameter is about 84.82 feet. (C = d x Pi).
Circumference of a circle = 2*pi*radius or pi*diameter
The answer depends on what the 27' refers to: the radius, diameter or circumference of the pool. A pool which is 27' across will cover 572.6 square feet.
Circumference = 18 feet.Depth = not known.
Circumference of the circular pool: 20*pi feet
