1. Graphing Relationships

2. Circles and squares Find a picture of four different size circles and four different size squares Find a picture of four different size circles and four different size squares

3. Data for Circles – measure each radius and record it The circles: radius, circumference and area The circles: radius, circumference and area Circle Radius of circle R Circumf C = 2  R Area A =  r 2 1 2 3 4

4. Data for Squares - measure the side length of each and record it The length, perimeter and area of the squares The length, perimeter and area of the squares Square Side Length L Perimeter P = 4L Area A = L 2 1 2 3 4

5. Graphing The Information Graph the relationship of the radius to the circumference of the circles Graph the relationship of the radius to the circumference of the circles Graph the relationship of the radius to the area of the circles on the same graph Graph the relationship of the radius to the area of the circles on the same graph You may be able to use a graphics calculator for this part, or your teacher will provide graph paper You may be able to use a graphics calculator for this part, or your teacher will provide graph paper

6. Graphing The Information Graph the relationship of the side to the perimeter of the squares Graph the relationship of the side to the perimeter of the squares Graph the relationship of the side to the area of the squares on the same graph Graph the relationship of the side to the area of the squares on the same graph You maybe able to use a graphics calculator for this part, or your teacher will provide graph paper You maybe able to use a graphics calculator for this part, or your teacher will provide graph paper
