A 15 mile radius implies 30 miles across.
Not sure what you are asking. A 12 mile by 12 mile square would be 144 square miles.
You can't put miles in terms of square miles because miles is length and square miles is area, its like comparing oranges and apples. A square mile is a mile in length and a mile in width.
There are 5280 ft. in a mile. So if your question is how many square miles are in a mile, there aren't any.
That's not a valid question. A mile measures length, a square mile measures area.
The area of a circle with a 6-mile radius is approximately 113 square miles.

283,131 sq miles
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).

It is 502655 sq miles, approx.
A circle with a mile radius has an area of pi sq miles.
There are pi*r^2 = 2827 square miles, approx.
The area of a circle with a 25-mile radius is about 1963.5 square miles. This calculation is based on the formula A = πr^2, where A is the area, π is approximately 3.14159, and r is the radius of the circle.
The formula for the area of a circle is: 3.14 (pi) times the radius squared. A circle with a 40 mile radius would have an area of 3.14 x 40 x 40 = 5024 square miles.
A circle that encloses 1,100 square miles of area has a radius of 18.712 miles .
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
