The "correct" unit will depend on the order of magnitude of the circle that you are trying to measure.
If drawn on a page, the radius is likely to be measured in inches or centimetres. In this case, the area should be given in square inches or square centimetres. But you may want more precision and measure the radius in millimetres and then the area should be in square millimetres.
A circle drawn in a field may be measured in feet, yard or metres and its area would then be in square feet, sq yards or sq metres.
The radius of the effective reach of a radio beacon may be measured in miles or kilometres and the area would then be in sq miles or sq km.
Yes, it is the same thing.Finding the square (unit of measure) is just like finding the area of a circle.You find it just like how you find area (3.14 x radius squared).
A circle can have a unit of length which could be either a measure of its diameter or radius, or of its circumference. Or the circle could have the unit of area.
The area of a 6 unit circle is: 28.27 square units.
To calculate the area of a unit circle you should use the equation x2+y2=1. The unit circle equal area of 1. You can find out more information on the mathisfun website for deeper explanation.
A 1.4-unit diameter circle has an area of 1.539 square units.

Area = pi*112 = 380.133 square cm rounded to 3 decimal places

A 10.25-unit diameter circle has an area of 82.516 square units.
A 1.4-unit diameter circle has an area of 1.539 square units.
A unit circle is not normally called 2 pi. Because the radius length measure of the unit circle is 1 unit, then the circumference of a unit circle is 2*pi, and its area is pi.
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
The area of a circle with a 22-unit circumference is 38.515 square units.
A circle with a radius of 1 unit has an area of 3.14 square units.
The surface area is measured in square units
