To find the area of a circle, you can use the formula ( A = \pi r^2 ). A 4-mile circle has a radius of 2 miles (since the radius is half the diameter). Converting miles to acres, 1 square mile equals 640 acres; thus, the area is approximately ( \pi \times (2^2) \approx 12.57 ) square miles. Multiplying this by 640 acres per square mile gives roughly 8,064 acres in a 4-mile circle.
circumference of a circle = 2*pi*radius or diameter*pi
Circumference of the circle = 1 times pi in miles
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 ?

113.097 square miles or 3.15296e9 square feet.
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.
The circumference of a circle with a 21 mile diameter is 66 miles (approx).
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

It is 6.3 miles, approx.
d = 0.31831 miles.
A circle with a mile radius has an area of pi sq miles.
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.
