PPT-9.1 – 9.2 Exploring Circles

Geometry ObjectivesAssignment Find the circumference of a circle Use circumference to solve other problems Definitions Circle is the set of all points in a plane that are equidistance from a given point on that plane. We start with the circle in the xy plane that has radius and is centred on the origin This is easy to parametrize r cos sin Note that we can check that r lies on the desired circle by checking 64257rstly that r lies in the correct plane in this Ms. . Andrejko. Vocabulary. Radius-. a segment with endpoints at the center and on the circle. Chord-. segment with both endpoints on the circle. Diameter-. chord that passes through the center and has endpoints on the circle. make. . earrings. . from. PET . bottles. We. . need. : . Empty. PET . bottles. Scissors. and . pliers.
