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.
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)
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 you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square 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 .
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.
A circle with an area of 100 square miles has a radius of 5.6418 miles. Or, 5 miles, 1,129 yards, 1 foot, 8.5 inches - more or less.
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 any circle is (pi) times (square of the radius)."Pi" is about 22/7, or 3.1416 .We can't calculate the answer for the given circle, because we're not sure what is meant by"a 2.4 mile circle". Does that mean the radius is 2.4 miles ? The diameter ? The circumference ?
You're talking about circular areas.-- The area of a circle is (pi) x (radius)2 .-- The area of the 4-mile radius is (pi) x (4)2 = 16 pi square miles-- The area of a circle is proportional to the square of its radius.So the area of the 40-mile radius is (10)2 = 100 times the area ofthe 4-mile radius = 1,600 pi square miles.The larger circle has (99 times the area of the 4-mile radius) more areathan the smaller circle has.(99) x (16 pi) = 1,584 pi = 4,976.3 square miles more than the smaller circle.
Use the formula for the area of a circle: area = pi x radius2. Then convert square miles to acres.
