what is the circumference of a circle whose radius is 10 cm

Sagot :

Circumference = 2π r

where π = 3.14 (pi)
         r = radius (half of diameter, if diameter is given instead of radius)

Circumference = 2 (3.14) (10 cm)
                      = (6.28) (10 cm)
                      = 62.8 cm  FINAL ANSWER
