Answer:

25.12 cm

Step-by-step explanation:

Circumference = 2[tex]\pi r[/tex]

We know that the radius is equal to 4cm.

We have to multiply  [tex]\pi[/tex] ( 3.14 ) by 2.

3.14 x 2 = 6.28

The next step is to multiply it by the radius.

6.28 x 4 = 25.12

The circumference of the bottom of the teacup is 25.12 cm.
