### How do you use circle formula?

Remember that the circle formula is (x – h)2 + (y – k)2 = r2. If you end up with an equation like (x + 4)2 + (y + 5)2 = 5, you have to keep straight that h and k are subtracted in the center-radius form, so you really have (x – (–4))2 + (y – (–5))2 = 5. That is, the center is at the point (–4, –5), not at (4, 5).

### How do you find the equation of a circle on a graph?

The equation of a circle appears as (x – h)2 + (y – v)2 = r2. This is called the center-radius form (or standard form) because it gives you both pieces of information at the same time. The h and v represent the coordinates of the center of the circle being at the point (h, v), and r represents the radius.

### How do you draw a curved line in coding?

• Use bezier() when you need long, smooth curves.
