How many acres in circle with a 6 mile radius?

Answer 1

Assuming a flat surface (no hills or depressions)

Area of a circle = π r2

Area of a circle = 3.14159 * radius square

Radius square = lineal meters * lineal meters

1 mile = 1,609 lineal meters

6 miles = 9,656 lineal meters

Area of circle with a 6 mile radius = 3.14159 * 9,656 * 9,656

Area of circle with a 6 mile radius = 292,920,754 square meters

1 Acre = 4,046.8564 square meters

Total acres in a circle with a 6 mile radius = 72,382.2947

Answer 2

That depends on the shape of the area. So we don't get confused, I want to differentiate the two separate meanings of the word "area" used here. One means a bounded piece of land, and I will call that a "plot". The other is the mathematical measure of the size of a bounded piece of land expressed in square units, and I will refer to that as "area". If the plot is a rectangle 1 foot wide and 1,583 feet long, the area is 1,583 square feet, or approximately 0.036 acres. If the plot is a rectangle 100 feet by 1,484 feet, the area is 148,400 square feet, or about 3.41 acres. If the plot is a 792-foot square, the area is 627,264 square feet, or 14.4 acres. If the plot is a perfect circle with a radius of approximately 504.2 feet, the area is approximately 798,648 square feet, or approximately 18.33 acres. This is the largest possible area for a plot with a circumference of 0.6 miles. There is, of course, an infinite number of shapes this plot can take, so it is impossible to determine the area without knowing the shape of the plot.

Answer 3

A circle with a 6-mile radius has an area of approximately 113.1 square miles. To convert this to acres, you would multiply by 640 (since 1 square mile is 640 acres). So, a circle with a 6-mile radius would be around 72,384 acres.

Answer 4

A circle with a circumference of 6 miles contains: 1,833.56 acres.

Answer 5

Approximately 72,382.3 acres.
