Parts of a Circle :

  • Radius
  • Diameter
  • Center
  • Circumference : The distance around a circle, usually presented as a C.

This is a linear measurement :

Pi : is the ratio of the circumference of a circle to its diameter.
Pi = C/D, where C = circumference and D = diameter
Pi is approximately 3.14

Pi = C/D
C = Pi x D
D = C/Pi
D = 2(r)


Find the circumference of each circle. Use the formulas above to answer the question.

1. C = Pi x D
= 3.14 x 40
= 125.6 mm

2. C = Pi x 2(r)
= 3.14 x 2(16.8)
= 3.14 x 33.6
= 105.504 cm

3. C = Pi x D
= 3.14 x 12.6
= 39.6 m

4. C = Pi x 2(r)
= 3.14 x 2(32.6)
= 3.14 x 65.2
= 204.728 m
