Answer 1

Answer:

31.4 cm

Step-by-step explanation:

C =

$2\pi \: r$

=> 2 × 3.14 × 10/2

=> Circumference = 31.4 cm

Answer 2

Answer:

The circumference of circle is 31.4 cm

Step-by-step explanation:

diameter = 10 cm

radius = d/2 = 10/2 = 5 cm

circumference of circle = 2πr

                                     = 2 x 3.14 x 5

                                     = 10 x 3.14

                                     = 31.4 cm
