Area of a circle is PI X R2
or in this case 3.14159265359 * (150/2)2
= 17,671.46 square miles (rounded to 2 decimal places)
12000 square miles
0.12 square mile.
657,740 sq mile
They cannot be compared. A mile is a measure of how long something is. A square mile is an area which is the same as the area of a square where each side is one mile.
Miles measures distance. Square miles measures area. Therefore, you can not compare the two.
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)
A circle with a mile radius has an area of pi sq 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.
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.
Area of a circle = (pi) R2 = (21)2 pi = 1,385.4square miles (rounded)
1 square mile = 640 acres.Area of a circle = (pi) (radius)2Area = (pi) (0.5)2 = 0.25 pi = 0.7854 square mile = 502.655 acres. (rounded)
A circle that encloses 1,100 square miles of area has a radius of 18.712 miles .
314.159 sq miles
Area of a circle = (pi) R2 = (pi) (1)2 = (pi) square miles 1 square mile = 640 acres (pi) square miles = 640 (pi) = 2,010.62 acres (rounded)
