Circle
Find circle areas and circumferences, then combine curves and shapes in composite figures.
Your child learns why a circumference is pi times the diameter and why an area is pi times the radius times the radius. From there, your child finds the perimeter of semicircles and quarter circles, works on composite figures, reads a hidden radius from a shape that fits, and compares two shaded regions without finding the piece they share.

About this chapter
These Primary 6 circle questions start with the circumference and area of a whole circle, move on to semicircles and quarter circles, and finish with composite figures built from squares, rectangles, triangles and parts of circles. Each page takes one kind of question, names the step children most often miss, and shows the working in full.
Practise by question type: area of a circle questions, circumference of a circle questions, area of composite figures with circles, perimeter of composite figures with semicircles, p6 circle mixed practice questions, circles inside squares shaded area questions, overlapping circles shaded area difference, perimeter of semicircles and quarter circles and finding the radius or diameter questions.
