Diameter resources

In this practical task, students measure two circular objects to find the circumference, diameter and the relationship between them (pi).

Students use the angle-in-a-semicircle property, and the sum of the angles in a triangle to find unknown angles.

Students identify the parts of a circle that lines on familiar signs and objects make.

Students use known diameters of tins to work out the floor area of a carton and a given number of tins.
