If the table is circular, then its circumference is 18.845 (rounded) If it's not a circle, then the circumference can't be calculated knowing only the area.
Circumference = 72*pi
A circle or ellipse has a circumference. A number, such as 9, does not.
If a circle has a circumference of 9, the diameter is: 2.864
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
If the table is circular, then its circumference is 18.845 (rounded) If it's not a circle, then the circumference can't be calculated knowing only the area.
The area of a circular table with an 18-foot circumference is 25.783 feet2
Circumference = 72*pi
The circumference of a 9 circle is: 28.3
A circle or ellipse has a circumference. A number, such as 9, does not.
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a circumference of 9, the diameter is: 2.864
circumference = 2*pi*9
circumference = 2*pi*9 inches
A circle with a diameter of 9 feet has a circumference of about: 28.27 feet (diameter x Pi = circumference).
Since Circumference = 2πr if the circumference is 9π r = 9π/2π = 9/2 = 4.5
9 times pi equals 28.274333882308139146163790449516. So, its circumference is 28.274333882308139146163790449516
