The radius of a circle with an area of 1,808.64 square miles is: about 24 miles (23.994 miles).
pi square miles.
The radius is half the diameter so the radius is ALWAYS half the diameter. Just because a number is odd doesn't mean you can't take half of it. For example if a diameter is 5 miles, then the radius is 2.5 miles.
103,000 square kilometers = 39,768.5 square miles.
Alameda County has about 738 square miles of area.
20 nautical miles
24 miles
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).
A circular area of 5 miles radius covers 50265.5 acres(to 1 dp) Area = pi*radius2, which with radius in miles will give you area as 78.53982 square miles, then multiply by 640, since there are 640 acres in 1 square mile.
The radius of Jersey, the largest of the Channel Islands, is approximately 46.5 square miles (or 120.5 square kilometers) in area. However, if you're asking about its radius as a circular measurement, the average radius would be around 4.5 miles (7.2 kilometers) from the center of the island to its coastline. Jersey is roughly oval-shaped, so its dimensions can vary.
Radius is the square root of 1808.64/pi = about 24 miles
In order to do this, you must have the radius in feet.-- Square the radius (multiply it by itself)-- Multiply the answer by 'pi'. (3.142 is close enough)-- The answer is the area of the circle, in square feet.
If the surface area of the moon is 14,650 square miles then its radius would be 34.144 miles.
A circle that encloses 1,100 square miles of area has a radius of 18.712 miles .
The area of a circle with a 6-mile radius is approximately 113 square miles.
Area, A, of a circle: A = (pi)r^2 r^2 = A/pi r = √(A/pi) r = √(1808.64/pi) r ≈ 23.9939 miles * so i would round it up and it would be 24miles * You can round the answer up to 24, but a radius 24 is not so close to the area which is 1808.64. Check: (pi)24^2 ≈ 1809.56, and (pi)23.9939^2 ≈ 1808.64
Radius = 4.068 miles (to 3 dp)
A circle with a radius of seven miles has an area of ~153.938 square miles.
