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.
