Square mile to mile radius?
A circle with a mile radius has an area of pi sq miles.
How many acres are in a circle with a radius of 0.5 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)
The area to an 80 mile radius?
The area of a circle is: pi times radius^2
How long is the radius of a 5 square mile circle?
The radius is 1.261 miles.
How many square miles in a 40 mile radius?
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.
Square mile to mile radius?
A circle with a mile radius has an area of pi sq miles.
How many acres are in a circle with a radius of 0.5 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)
How long is the radius of a 5 square mile circle?
The radius is 1.261 miles.
The area to an 80 mile radius?
The area of a circle is: pi times radius^2
How many Acres in a circle 2.5 mile radius?
1 sq mile = 640 acres area circle = π × radius² = π × (2.5 miles)² = π × 6.25 sq miles = π × 6.25 × 640 acres = 4000π acres ≈ 12,566 acres.
What is the circumference of a 7 mile circle?
circumference of a circle = 2*pi*radius or diameter*pi
How many acres in a 1 mile radius circle?
Use the formula for the area of a circle: area = pi x radius2. Then convert square miles to acres.
How many square miles in a 10 mile circle?
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 diameter of a circle is twice the radius the radius of the circle is?
1/2 of the diameter
How many square miles in a 40 mile radius?
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.
How many acres in 1 mile circle?
I have this same question so I'll try to work it out and answer it: The perimeter of the circle is 5,280 feet. Area of circle = 3.14 times radius squared. We don't have the radius, but the sides of a square mile is 5,280. 640 acres are in a mile and 43,560 sq ft are in an acre, so when we multiply those figures we get 27,878,400 sq ft. So now we simply work the pie formula backwards............ 27,878,400 divided by 3.14 = 8,878,471 then we find the sq root of 8,878,471 which = 2,980 2,980 = radius. So we've basicly just reminded ourselves that there are 640 acres in 1 sq mile. But what about a circle mile? The percentage of a circle that fits in the smallest possible square is 78.6%. So finally we multiply .786 by 640 acres and get our answer. The number of acres in a 1 mile circle is............................................ 503 acres.
What is the radius of a circle?
The radius of the circle is the length between the middle of the circle and any of the sides. It is also half the lenght of the diameter.
