It covers an area of 218 square miles and its radius is 10 miles long , so I hope that answers your question.
square miles and radius have different units
The radius of a circle with an area of 1,808.64 square miles is: about 24 miles (23.994 miles).
Radius is the square root of 1808.64/pi = about 24 miles
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 .
Radius = 4.068 miles (to 3 dp)
A circle with a radius of seven miles has an area of ~153.938 square 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.
This is the area of a circle with a radius of 100 miles →area = π × radius² = π × (100 miles)² = 10,000π sq miles ≈ 31416 sq miles
The radius is 1.261 miles.
A circle with a radius of 10 meters has an area of 314 square meters.
