6th Grade Measurement
posted by Missy on .
What is the area of the circle if the diameter is 6 m?
A: 9m
B: 18 m
C: 27 m
D: 108 m
I think the answer is B because if times the diameter by 3 then you get 18.

The answer isn't 18. After looking at the material Ms Sue posted for the previous question, rework this one with that information.

Yes, I reworked it and I got 27 m.

I did this problem and I got 28.27...hm.. is my calculator incorrect?
I don't think so since I went to the site and the area of a circle is pi r^2
r= 3 and they have the same problem on the site that was given by Ms.Sue!... o.O;; 
Reading below, if you use 3 instead of 3.14..etc.
then you get 27 so that is correct. =D 
i need help
