B.2 mm
C.4 mm
D.8 mm

Answer 1

\[\huge\rm C = \pi \times d\] if you have diameter
use thsi formula to find C

Answer 2

i got 12.56???

Answer 3

and none of them is right answer :D

Answer 4

im confused these were the only choices

Answer 5

wait

Answer 6

I got 12.56 as well

Answer 7

so which one should i choose

Answer 8

you shouldn't....they are all wrong...tell your teacher. Show the work you did and the answer you got, which was 12.56...thats what I would do

Answer 9

they forgot to write pi i think

Answer 10

the problem is im homeschooled and these are online classes

Answer 11

yep 2 pi r is a formula
but when you divide diameter and then multiply by 2pi you should get same answer
so 12.57

Answer 12

so the answer is 2mm??

Answer 13

it can't be 2

Answer 14

could the answer be C and they just forgot to put pi ?

Answer 15

maybe just tell me one to choose

Answer 16

circumfence=diameter*pi or 2*radius*pi

Answer 17

\[\huge\rm C = \pi \times d \]
diameter is 4mm
so replace d by 4
i don't if you have to use pi or not
bec none of the answer choice have pi

Answer 18

i tink C if guessing they forgot to write pi

Answer 19

lol...I would put C and then write multiplied by pi (3.14)

Answer 20

maybe it didn't copied

Answer 21

Answer 30

haaha

Answer 31

that's not a little mistake \[C = \pi \times d\]
is not equal to 4mm
