Lesson 9.3A R.4.G.6 Solve problems using inscribed and circumscribed figures

 Inscribed Polygon: A polygon drawn inside a circle with all of its vertices on a circle  Circumscribed Polygon: A polygon drawn outside a circle with all of it sides on a circle

 Using the circle below and rounding to the nearest tenth, find: a) The circumference of the circle b) The area of the circle 12 5

 Using the circle below and rounding to the nearest tenth, find:  The circumference of the circle  The area of the circle 35 12

 Using the circle below and rounding to the nearest tenth, find:  The circumference of the circle  The area of the circle 11

 Rule: Two intersecting tangent segments are congruent 14
