22 cm

Step-by-step explanation:

Circumference = pi × diameter

Circumference = pi × 7 cm

Circumference = 22 cm

Answer 2

Answer:

The circumference of the circle = 22cm

Step-by-step explanation:

given : the diameter of circle ( d )= 7cm

         => the radius of circle ( r ) = d/2

                                                     = 7/2 cm

Now, the circumference of the circle

                    = 2πr

                    = 2 x 22/7 x 7/2

                    = 22cm.
