[FONT=Tahoma][SIZE=3]( i ) the circumference of a circle ( c = 2 x 3.14 x r) is related to the radius of the circle in a direct way. Draw the circles as indicated int he table below, then measure the circumference?
( ii ) calculate the ratio circumference divided by radius is related to the formula
Circle Radius r (mm) Circumference C (mm) Circumference ÷ radius
( iii) explain how these results help to determine the formula for the circumference. That is, explain how the ratio circumference ÷ radius is related to the formula ?
