Circumference of the circle: 38*pi in miles
Diameter of the circle: 31.4/pi = 10 miles rounded up
Circumference of the circle = 1 times pi in miles
Circumference of a circle is equal to pi*diameter, so if d=9miles, c=28.3miles (to 1dp).
d = 0.31831 miles.
The circumference of a circle-shaped lake with a diameter of 2 miles is: 6.283 miles (diameter x Pi = circumference).
Circumference of the circle: 38*pi in miles
The diameter of a circle who's circumference is 28.26 miles is: nine (9) miles
Diameter of the circle: 31.4/pi = 10 miles rounded up
24888.93 miles
Circumference of the circle = 1 times pi in miles
The circumference of a circle with a 21 mile diameter is 66 miles (approx).
Circumference of a circle is equal to pi*diameter, so if d=9miles, c=28.3miles (to 1dp).
49 times pi
It is 6.3 miles, approx.
d = 0.31831 miles.
That depends on whether 10 miles is the diameter or circumference.
