  1. 4. A slice of a circle, formed between two radii.
  2. 6. The total distance around the outside of a shape.
  3. 8. The formula to find the circumference of a circle, given by C=2πr or C=πd, where C is the circumference, r is the radius, and d is the diameter.
  4. 10. A unit used to measure area, such as square centimetres (cm2) or square meters (m2).
  5. 12. A round shape with all points equidistant from the center.
  6. 14. Changing the units used to measure area, for example, converting square meters to square centimeters.
