How many square miles are in a radius mile?
So what shape is the surface inside a circle — a disk. And which formula gives a disc’s area — π×(radius)2 = 3.1416 × 122 = 3.1416 × 144 etc. If a person can see for a distance of 12 miles, he/she can see the same distance in any direction. Therefore, he can see pi 12^2 = 144 pi square miles.
How do you calculate square miles from radius?
Multiply Pi (3.1416) with the square of the radius (r) 2. The radius can be any measurement of length. This calculates the area as square units of the length used in the radius.
