The area of a 27 feet diameter circle: pi*13.5^2 = 573 square feet rounded
A circle with a 27-foot diameter has an area of 572.56 square feet.
Its circumference is 27*pi = 84.823 mm rounded to 3 decimal places
Area = 3.976 square feet
The circumference of a 27-foot diameter circle is about 84.82 feet. (diameter x Pi = circumference).
If 27 inches is the diameter, then that is the diameter. If 27 inches refers to the radius, you must multiply it by 2 to get the diameter.

The circumference of a circle with a 27 foot diameter is about 84.82 feet. (C = d x Pi).
Area of a circle = pi*radius2 Area = pi*13.52 = 572.5552611 or 573 square feet to the nearest square foot.
The Area of a circle = pi x r x r where pi = 3.14 and r is half the diameter or 13.5 feet A = 3.14 X 13.5 X 13.5 = 572.3 sq. feet
What is 27 X 3.14? 27 pi
Wait, what? I believe diameter is the measurement straight across the middle of a circle, not a unit of measurement. So if a circle were to be 27 inches in diameter, it would be 27 inches from one side of the circle to the other, with the line going exactly through the center of the circle. Basically, cutting the circle in half.
