area = pi x radius squared = 3629.84; pi = 3.14; radius = square root of (area/3.14) = 34 mies
It is 33.9914, approx.
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).
That depends whether the "10-mile circle" refers to the circle's radius, its diameter, or its circumference. Assuming it is the diameter, divide it by 2 (to get the radius), then use the formula: area = pi x radius2.
That depends on whether 10 miles is the diameter or circumference.

A circle with a radius of seven miles has an area of ~153.938 square miles.
Radius is the square root of 1808.64/pi = about 24 miles
The radius of a circle with an area of 1,808.64 square miles is: about 24 miles (23.994 miles).
Radius = 4.068 miles (to 3 dp)
A circle that encloses 1,100 square miles of area has a radius of 18.712 miles .
The radius is 1.261 miles.
A circle with a radius of 11.5 miles has an area of 415.48 square miles.
A circle with a mile radius has an area of pi sq miles.
64pi (miles square)
If the area is a circle and the radius of the circle is 21 miles, the distance around the circle (circumference) is 131.95 miles. The area of that circle is 1,385.4 square miles.
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.
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.
