Having investigated the relationships between the radius, diameter, circumference and area of a circle, I can apply my knowledge to solve related problems. MTH 4-16b
In this topic we will extend our knowledge of the circle by learning how to calculate the length of an arc of a circle and calculate the area of any sector of a circle given the angle at the centre. We will use our knowledge to solve problems including finding the angle at the centre given an arc length or sector area.
Homework: Arcs & Sectors
Task 1: Find the minor arc length for (c), (d) and (e), the sector area OAB for (f), (g) and (h).
Task 2: In your group solve the allocated problem, Q3, Q4 or Q5, and be prepared to present your solution to the class on the whiteboard.
