If the diameter of the circle is 18 feet, the circumference of the circle is 56.55 feet.
The circumference of a circle or ellipse in geometry is its perimeter. That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.
The diameter of a circle is 18 feet.
D = 18 feet
Now, the radius of the circle is half the diameter of the circle.
Therefore,
Diameter = 2 × Radius
Radius = Diameter / 2
D = 2r
r = D / 2
r = 18 feet / 2
r = 9 feet
Now, the circumference of a circle is given as:
Circumference = π × diameter
Circumference = π × 2r
Circumference = 2πr
Circumference = 2 × π × 9 feet
Circumference = 2 × 3.14159 × 9
Circumference = 56.55 feet
