A circle with a radius of 1.8 km has a circumference of 11.31 km
Circumference of circle: 2*pi*13.1 = 82.30972752 km
C = 31.4 km
If 11.6 km is diameter, then 11.6 * pi = 36.4425 km circumference If 11.6 km is radius, then 11.6 * 2 * pi = 72.8850 km circumference
radius = 48/2 = 24 km

The circumference of a circle with a radius of 1.5 km is: 9.425 km (C = r x 2 x Pi).
If 11.6 km is diameter, then 11.6 * pi = 36.4425 km circumference If 11.6 km is radius, then 11.6 * 2 * pi = 72.8850 km circumference
42 pi km ~ 131.946891
The circumference of a circle with radius of 7 km is 44.0 km (to the nearest tenth), and the area of a circle with radius of 7 km is 153.9 km (to the nearest tenth).C = 2 pi RA = pi R2
The circumference of a circle with a diameter of 16 km is: 50.3 km
If C = 449,000 km then radius = 71,500 km
If the area is a circle and the radius of the circle is 21 miles, the distance around the circle (circumference) is 131.95 miles. The area of that circle is 1,385.4 square miles.
