Question

Anyone know the answer to this?

Answer 1

hello again

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 * 6 = 12mm \\ v = \pi \: d \\ v = 12\pi \: mm`

i hope this is the answer
