What is the exact circumference of the circle?
A. 8 in
B. 16 in
C. 32 in
D. 48 in​

Half of 16 is 8 which is your radius,

8 x 3.14(pi) x 2(you always have to use this number because you just need it when solving circumference) = 50.24

Step-by-step explanation:

Formula of circumference:

radius(half of diameter or given radius) x pie/pi some people call it (3.14 or 22/7 use what is supposed to be used) x 2 (always 2)
