the radius of a circle is half the diameter, so half of 1.8 is .9. The radius is .9km.
The circumference of a circle with a diameter of 16 km is: 50.3 km
The circle's area is 22,698 km2
The answer depends on what is 10 km: the radius, diameter, perimeter. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
Circle's circumference: 4 times pi = 12.57 km rounded to 2 decimal places
60 mm, or 6 cm, or even 0.06 m, finally, and although correct most foolish, 0.00006 km. but you really should learn to do your math, not ask questions on answers.com
Then it will have a diameter of 16 km
radius = 48/2 = 24 km
9.4 km
A circle with a radius of 0.9 km has an area of 2.54 square km
half of d
The diameter of any circle is twice its radius. Therefore: 2 times 1737.4 = 3474.8 km.
The diameter of the Earth is 12742 km or about 8000 miles.
Radius = approx 6050 km, so diameter = 12100 km.
A circle with a radius of 1.8 km has a circumference of 11.31 km
Europa: 1561 km radius Earth: 6371 km radius The diameter is twice the radius.
A circle with a radius of 126 km has a circumference of 791.68 km.
The circumference of a circle with a diameter of 16 km is: 50.3 km
