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 ?
The area in acres is 125,653 9.
There are 1760 yards in a mile.
Using the formula for the area of a circle, πr2, the area is exactly 0.25π square miles.That's about 0.785 square miles. Since π is an irrational number, the exact area cannotbe written with numerical digits alone.
circumference of a circle = 2*pi*radius or diameter*pi
Circumference of the circle = 1 times pi in miles
A circle with a mile radius has an area of pi sq miles.
The area of a circle is: pi times radius^2
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.
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 area in acres is 125,653 9.
The area of a circle with a 6-mile radius is approximately 113 square miles.
If the area is a circle with a four-mile circumference, the area in acres is: 814.72 acres.
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).
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.
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 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.
