  2. CIRCLE 1. Basic terms • Radius (jari-jari) : any segment that joins the center to a point of the circle • Chord (tali busur): a segment that joins two points of the circle • Diameter (diameter) : is chord that contains the center of a circle • Arc (busur) : is part of a circle • Apotema (apotema) : is the distance from center to chord (it must perpendicular to chord) • Segment (tembereng) : an area bounded by chord and an arc of the circle • Sector (juring) : an area bounded by two radii and an arc of the circle Arc : Example Radius : OA, OB, OC, OD, OE, OF Arc B Sector C Chord : FE, AF, AD Diameter : AD O  A D Apotema : OG G Segment : FE E Sector : OBC Segment F

  3. 2. Circumference and Area of Circles Formula: Circumference (Keliling) or Area (Luas) or C = Circumference A = Area D = Diameter r = Radius D = 2 r
