Question 965514: Bethany divided a circle with a radius of 7 inches into 6 equal sectors. What is the area of one of the sectors?
A. 12/7 in^2
B. 14/6 in^2
C. 36/7 in^2
D. 49/6 in^2
I thought that it would be 42, but that's not in the answers. So I think it would be C, but if not, possibly D? Thank you!
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! the area of a circle is pi * r^2.
the area of your circle would be pi * 7^2 = 49 * pi.
1/6 of that area would be 49/6 * pi.
your solution would be 49/6 * pi.
that would be selection D if all those selections were * pi.
6 * 7 would not be correct.
the formula for the area of a circle is pi * r^2.
if you have 6 sectors, and all those sectors are the same size, then the area of each of those sectors has to be the area of the circle divided by 6.
