              Problems with Circular Shapes

              Students use the circumference and area of a circle to solve a variety of problems with circular shapes.  Throughout the lesson students develop their calculator and non-calculator techniques as solutions are presented in terms of pi or decimals rounded to three significant figures.The start of the lesson recaps finding the circumference and area of a circle as a decimal and in terms of pi.  The plenary challenges students students to calculate the perimeter and area of a circle and semi-circle.
