Then it will have a diameter of 16 km
A circle with a radius of 1.8 km has a circumference of 11.31 km
A circle with a radius of 126 km has a circumference of 791.68 km.
radius = 48/2 = 24 km
The radius is 71,461 km
A circle with a radius of 0.9 km has an area of 2.54 square km
C = 31.4 km
the radius of a circle is half the diameter, so half of 1.8 is .9. The radius is .9km.
The radius is 8 inches.
Circumference of circle: 2*pi*13.1 = 82.30972752 km
9.4 km
Radius of circle: 8/2 = 4 inches
The circle's area is 22,698 km2
