The formula for the circumference of a circle is:
C = πd
Where C = circumference, d = diameter, and π (pi) is a mathematical constant that is approximately equal to 3.14.
We can rearrange this formula to solve for the diameter:
d = C/π
Plugging in the given circumference of 80ft, we get:
d = 80/π
Estimating pi to be 3.14, we can approximate the diameter as:
d ≈ 80/3.14
d ≈ 25.5 ft
Therefore, the estimated diameter of a circle with a circumference of 80ft is approximately 25.5 feet.
