In this question, you have a large circle A with a radius of 6.5cm and a small circle B with radius 2.3cm. Calculate the area of the two circles. Once you have calculated the areas, take the area of circle A and subtract the area of Circle B and that will give you the area of the purple shaded region.

116.113cm2 is the purple reigon area

Step-by-step explanation:

using pi r squared

1st circle area: 16.619

2nd circle area: 132.7322

1st - 2nd = 116.113 cm2

• before the lesson, students attempt the assessment task individually. you then review students’

solutions and formulate questions that will them improve their work.

• during the lesson, students work collaboratively in pairs or threes, plotting graphs, completing

tables of values and deducing equations. then, based on the number of common solutions,

students link these representations.

• in a follow-up lesson, students receive your comments on the assessment task and use these to

attempt the similar task, approaching it with insights gained from the lesson.
