Content description
Investigate the relationship between features of circles such as circumference, area, radius and diameter. Use formulas to solve problems involving determining radius, diameter, circumference and area from each other
Elaborations
investigating the circumference and area of circles with materials or by measuring, to establish an understanding of formulas
investigating the area of circles using a square grid or by rearranging a circle divided into sectors
solving problems given one of radius, diameter, circumference or area of a circle, then the other quantities are determined from this
