Answer 2

hint:
we can apply this formula:
\[\huge C = 2\pi r = \pi d\]
where \(d\) is the diameter

Answer 3

im confused

Answer 4

why?

Answer 5

what does r represent?

Answer 6

we have \(2r=d\)
so we can write:
\[\huge C = 2\pi r = \left( {2r} \right)\pi = d\pi = \pi d\]
r is the radius of the circumference

Answer 7

is it 12π

Answer 8

that's right!
