Find the circumference of the circle. Round to the nearest tenth. The middle of the circle is 44mm
1. A
2. D
3. A
4. C
is Kinsey right????????????????????wtf
Does middle of circle mean diameter or radius?
I guess...
If 44 mm is the diameter >>
C = pi * r^2
C = 3.14 * 22^2
c = 1519.8 mm

Not sure, it has a line through the middle of the circle with 44mm
Study the site I posted for pictures of a diameter, a radius, and a circumference.
Does the line cut the circle in half? If so, it is a diameter. Otherwise it would be a radius.
C = pi * d
Or C = 2 * pi * r
d represents length of diameter and r represents length of radius.
Use 3.14 for pi.
Ok thank you all. I got 138.16
So I round it 138.2
yes kinsey is right i just got a 100% on connexus algebra :D
Oops -- I was wrong. Thanks for correcting me, rbowh.
I was finding the area, not the circumference.
C = 3.14 * 44
C = 138.2
