Beyond the Answer
To convert the given equation of the circle from general form to standard form, you can complete the square for both
Starting with the equation
Next, complete the square for
- Take half of 6 (which is 3), square it (gets 9), and add it:
Then, complete the square for
- Take half of -4 (which is -2), square it (gets 4), and add it:
Incorporating these adjustments into the equation, it becomes:
Thus, the standard form of the circle’s equation is:
Now for the circle’s features: a circle’s radius is the square root of the number on the right side of the equation! In this case, the radius is 3, which can lead to fun activities like drawing a perfect circle with a compass!
And speaking of circles, did you know that circles have been a part of human history for thousands of years? Ancient civilizations, from the Babylonians to the Greeks, studied circles and developed the mathematical principles we still use today. The fascination with this shape is woven into our fabric, influencing art, architecture, and even science.
