  4. Circles Vocabulary • Radius The radius of a circle is the distance from the center of the circle to the outside edge. It is ½ the Diameter r = d ÷ 2 Free powerpoint template: www.brainybetty.com

  5. Circles Vocabulary • Circumference The circumference of a circle is the perimeter -- the distance around the outer edge. 2πr Free powerpoint template: www.brainybetty.com

  6. Circles Vocabulary • Area of a Circle Area = πr2Area = where r = the radius of the circle & π = 3.14 A = πr2 Free powerpoint template: www.brainybetty.com

  7. Circles Vocabulary • The Chord of a Circle A chord of a circle is a line segment that connects one point on the edge of the circle with another point on the circle. The diameter is a chord -- it's just the longest chord!) Free powerpoint template: www.brainybetty.com
