CHAPTER AT A GLANCE
Areas Related to Circles
•Unit: Mensuration
•Board weightage: Mensuration (this chapter together with Surface Areas and Volumes) carries about 10 marks out of 80; this chapter usually gives one 3-mark or 4-mark question and sometimes a short question (please check the latest sample paper)
•This textbook edition covers: length of an arc, area of a sector and area of a segment of a circle. Areas of combinations of plane figures are not in this edition.
•Most scoring part: it is formula based; the area of the triangle in the segment formula is where marks are lost
