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 in acres is 125,653 9.
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.
If the circle's diameter is two miles, the area would be: 8042 acresA diameter radius of two miles is 12.5 square milesIf the circle's circumference is two miles, the area would be: 203.7 ac
The circumference of a circle with a 21 mile diameter is 66 miles (approx).
