1. CIRCUMFERENCE OF A CIRCLE LEARNING TARGET 4: I CAN SOLVE PROBLEMS USING AREA AND CIRCUMFERENCE OF A CIRCLE.

2. CARNEGIE 12.2 # 15 The circumference of a circle is 112.8 mm. Calculate the diameter of the circle using the circumference formula. Let π = 3.14 Circumference= π * Diameter 112.8 mm = 3.14 * Diameter (Since 3.14 is multiplying by the Diameter we need to divide by 3.14) 112.8 mm = 3.14 * Diameter 35.9 mm = Diameter 2 3.14
