The equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2. Now, this equation may look like it would take an eternity to understand, but it’s very simple. H and K in the equation stand for the point in the middle of the circle. See this picture? H and K are the coordinates for the middle of the circle.
R stands for the radius and ^2 stands for the second power. With this equation, you can graph a circle on a graph with no problem! 😀 This shows that you can create shapes by using an equation.

Math, is thing I love but dont know how to do
Steve Hawkins would be so proud of you. Yes, math is not just equation of variables, functions, numbers and math operators. There is a visual part as well. Math is truly a science and an Art rolled into one.
