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.
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).
The area doesn't tell you the perimeter.-- If the square mile is inside a circle, then the perimeter (circumference) is 3.545 miles.-- If the square mile is inside a square, then the perimeter is 4.000 miles.-- If the square mile is inside rectangle that's 2 miles long and 1/2 mile wide,then the perimeter is 5.000 miles.-- If the square mile is inside a rectangle that's 10 miles long and 0.1 mile wide,then the perimeter is 20.2 miles...etc.The area doesn't tell you the perimeter.
Miles measures distance. Square miles measures area. Therefore, you can not compare the two.
283,131 sq miles
A 12-mile line has an area of 0 square miles. A 12x12 mile square area has an area of 144 square miles, if that's what you meant. When you're talking about area, you need a length and a width.
The area of a circle with a 6-mile radius is approximately 113 square miles.
113.097 square miles or 3.15296e9 square feet.
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).
Area of a circle = pi R2 = 9 pi = 28.27 square miles (rounded)
Area of a circle = pi R2 = 16 pi = 50.265 square miles (rounded)
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.
A circle with a mile radius has an area of pi sq miles.
A 1 mile radius circle covers approximately 3.14 square miles, which is equivalent to 2,008 acres.
The area of a circle with a radius of 150 miles is approximately 70,685 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.
A mile is the length of a line, square miles are the measure of area, typically of a square or rectangle
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.
