Remember the circle equation
C = pi d
This equation has come to us from Classical Antiquity.
pi = ~ 3.141592.
d = 80 m
Hence
C = 3.141592 X 80 m =
C = 251.32744123.... m
C ~ 251.3 m
NB Also remember the other circle equation for area
A = pi r^(2) , where 'r' is the radius of the circle ( d/2).
The circumference of a circle can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. For a circle with a diameter of 80 meters, the circumference is ( C = \pi \times 80 \approx 251.33 ) meters. Thus, the circumference is approximately 251.33 meters.
Divide the circumference by pi (~3.14) to get the diameter.
The three most common ways to describe the dimension or size of a circle is either the diameter or the radius or the circumference (perimeter).When the circumference is given then dividing that by Pi will give you the diameter (circumference / Pi = diameter).
The value of pi is constant. It is calculated by dividing the circumference of a circle by its diameter. As the circle's circumference grows, the diameter grows at the same rate, proportionally. This means that the circumference divided by the diameter (if measured precisely) will always yield pi. If it does not, it is not a perfect circle. The ratio between the circumference and the diameter of a circle will always stay the same, no matter how you change the size of the circle.
Circumference = π*d = π*80 = 251.33 units

The circumference of a circle is equal to pi times its diameter. Another way to say this is that for any circle, circumference divided by diameter will always have pi as the answer, regardless of the size of the circle.
Each circle with a different radius (or diameter or circumference) is a different size circle.

The answer requires information on the size of the circle: its radius, diameter or circumference.

Circumference = π*d = π*80 = 251.33 units
9 times bigger
Circumference = 2*pi*radius or pi*diameter
For any circle, whether its size is microscopic or astronomical, the ratio of its circumference to its diameter is always π. Although a transcendental number, its value is approximately 3.14
It depends on what you mean by a certain size circle. If the certain size is the diameter, then the answer is 54 inches. If the certain size is the radius, then the answer is 108 inches. If the certain size is the circumference, then the answer is 54 / 3.14159 or about 17.19 inches
