Answer:
D
Step-by-step explanation:
The formula to find the circumference of a circle is :
![c=2 ~pi~ r](https://tex.z-dn.net/?f=c%3D2%20~pi~%20r)
To find the radius we would divide 3.3 by 2
The radius is always HALF of the diameter.
3.3/2=1.65
Now we know r=1.65
So we plug that into the circumference formula:
![c=2(3.14)(1.65)](https://tex.z-dn.net/?f=c%3D2%283.14%29%281.65%29)
pi=3.14
Once you multiply all the numbers together you get:
C=10.36m
Answer:
1/3
Step-by-step explanation:
5 red marbles + 10 blue marbles = 15 total marbles
5 red marbles / 15 total marbles = 5/15
5/15 = 1/3
