What is the circumference of the circle? Use 3.14 for pi

r = 6.4 cm

20 096 cm

40 192 cm

200 96 cm

401 92 cm

40.192cm

Step-by-step explanation:

the circumference of a circle = ?

radius = 6.4cm

recall that,

circumference of a circle = 2πr

circumference of a circle = 2 x 3.14 x 6.4cm

circumference of a circle = 40.192cm

therefore the circumference of a circle whose radius is 6.4cm is evaluated to be equals to 40.192cm.

the answer to your question is option B 40.192cm

its

40 192 cm
