If area of a circle is A equals pi X the square root of -2 the quantity squared does one need to take out an imaginary number?
You will never have an imaginary number when finding the area of a circle. Never. Imaginary numbers came to be when mathematicians were upset that a negative number couldn't have a square root. You will usually find them when using the quadratic formula.
