Square mile to mile radius?
A circle with a mile radius has an area of pi sq miles.
Is 40 mile radius the same as 40 miles?
No, 40 mile radius is an area unit whereas 40 mile is distance. This means that something 30 miles from a location can be said to be in a 40 mile radius from that location.
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 a 5 mile radius?
A circular area of 5 miles radius covers 50265.5 acres(to 1 dp) Area = pi*radius2, which with radius in miles will give you area as 78.53982 square miles, then multiply by 640, since there are 640 acres in 1 square mile.
What is the area of a sector with a radius of 8 and an arc angle of 80 degrees?
Area = r2*A where A is the angle measure in radians. = 8*8*80*pi/180 = 89.361 square units.
Square mile to mile radius?
A circle with a mile radius has an area of pi sq miles.
What is a radius mile?
anything around the area.
What is the area growth from 3 mile radius to a 15 mile radius?
Area variesa s pi times the radius squared. 15/3 = 5; 5 squared = 25 A radius of 15 miles grows the area 25 times
Is 40 mile radius the same as 40 miles?
No, 40 mile radius is an area unit whereas 40 mile is distance. This means that something 30 miles from a location can be said to be in a 40 mile radius from that location.

An fm radio station signal travels in a 40 mile radius an am radio station signal travels in a 4 mile radius how much more area does the fm station cover than the am station?
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.
