Enter the length of the minor arc and the radius of a circle into the calculator. The calculator will display the inscribed angle of that circle. View the image below to understand what the inscribed angle is.

## Inscribed Angle Formula

The following equation can be used to calculate the inscribed angle of a circle and minor arc.

A = 90 * L / Pi*R

• Where A is the inscribed angle
• L is the length of the minor arc
• R is the radius
