Polar Graphing: Circles

---

Circles with center at origin

​Desmos File: Graphing r = a
Center AT origin (degrees)

click on lower right corner to use this online graphing calculator

• this allows you to plot circles with center at origin on the polar coordinate plane
• angles are measured in degree measures 

​Desmos File: Graphing r = a
Center AT origin (radians) 

click on lower right corner to use this online graphing calculator

• this allows you to plot circles with center at origin on the polar coordinate plane
• angles are measured in radian measures
