C = 9,525 miles D = 3,032 miles
d = 0.31831 miles.
Circumference of a circle is equal to pi*diameter, so if d=9miles, c=28.3miles (to 1dp).
Circumference is pi * d. Solve for d. d = Circumference / pi
The circumference of Earth is approximately 24,901 miles, and the diameter is about 7,917.5 miles.
The equatorial circumference of the Earth is approximately 24,901 miles.
Circumference = pi*d. So d = Circumference/pi
The equatorial circumference of Earth is approximately 24,901 miles.
The area of a circle with a circumference of 5 miles is approximately 1.26 square miles.
The circumference of a circle with diameter d is pi*d So if d = 8mi then circumference = 25.13 mi.
If the area is a circle, the circumference is 0.28 miles.
24,899 miles is the Equatorial Circumference Equatorial Circumference 40,075 kilometres 24,899 miles
