1 Chapter Graphs of Trigonometric Functions Answer Ke. Radian Measure Answers. π. π. π. π. 7π. π Multipling b π π is like multipling b the conversion factor of. Dividing b 0 gives ou the 80 0 fraction of the circle ou want. Multipling b π gives ou the measurement in terms of radians.. Multipling b 80 0 is like multipling b the conversion factor of. Dividing b π gives ou the π π fraction of the circle ou want. Multipling b 0 gives ou the measurement in terms of degrees.. A radian is the length of the radius of the circle. The circumference of a circle is πr, or π radius lengths. Therefore, the circle is π radius lengths or π radians. CK- Trigonometr Concepts
