-Problems on Length of Arc and Chords.
-Perimeter and Area of Sector and Segments of a Circle.
Parts (properties) of a circle are:
1.Circumference:This is the curved outer boundary of a circle.
2.Arc: Arc is a part/portion of the circumference of a circle
3.Major and Minor Arc: The chord which is not a diameter divides the circumference
into two arc of diff sizes: a major and a minor arc.
4.Radius: this is any straight line joining the centre to the circumference of a circle.
5.Diameter: A diameter is a chord which passes through the centre and divides the circle into 3 equal parts.
6.Chord: A chord of a circle is a line segment joining the centre is a line its
7.Sector: This is the region between two radii and the circumference.
8.Segment: it is the region between a chord and the circumference.
9.Major and minor Segment: The chord also divides the circle into two segments of difference sizes: major and minor segments
