Question

Anyone know the answer to this?

Answer 1

Answer:

hello again

Step-by-step explanation:

the radius of the circle is 6mm

for having the circumference we need diameter

for having diameter we should multiply in 2

so:

$d = 2r \\ \\ d = 2 \times 6 = 12mm \\ v = \pi \: d \\ v = 12\pi \: mm$

i hope this is the answer
