1
investigate the relationship between the diameter and circumference of a circle.

2
circumference – the perimeter of a circle diameter – the distance across a circle through the center radius – half the diameter Circumference & Diameter

3
Symbol for pi π π = circumference ÷ diameter = 3.14 Formula for finding the circumference of a circle is: C = π x d Want some pi?

4
Calculate the circumference of a circle with a diameter of 8.15 cm. C = π x d C = 3.14 x 8.15 C = 25.59 cm Example

5
Calculate the circumference of a circle with a diameter of 6.5 cm. C= 20.41 Calculate the circumference of a circle with a diameter of 62.5654 cm. 196.46 Your Turn

6
What do you do if you know the circumference and are trying to find the diameter? Use the following formula: d = c ÷ π Other Way
