MA412MG
Calculates the perimeters of plane shapes and the circumferences of circles
Outcomes
 Find perimeters of parallelograms, trapeziums, rhombuses and kites (ACMMG196)

Investigate the relationship between features of circles, such as the circumference, radius and diameter; use formulas to solve problems involving circumference (ACMMG197)

Develop and use the formulas to find the circumferences of circles in terms of the diameter d or radius r:
Circumference of a circle = pi x d
Circumference of a circle = 2 x pi x r
Examples

Find the perimeters of simple composite figures consisting of two shapes, including quadrants and semicircles
Examples

Develop and use the formulas to find the circumferences of circles in terms of the diameter d or radius r:
Circumference of a circle = pi x d
Circumference of a circle = 2 x pi x r
