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
