I can never seem to be able to answer on time.. When is the new riddle released?
the new one will be released today
Yeah I know... but at what time exactly?
the time is random, every wednesday a new one is released at different times
sorry!
It is released when the afternoon news go out, Usually 3-4 PM NST. Right now it's just now 3:00 pm NST. Within an hour or so.
hopefully very shortly now that its after 3:00 NST
In this diagram, the red part has an area of 800 square centimetres.
What is the area of the green part, in square centimetres? Please round up to the nearest whole number, and submit only the answer.

That's the new one. I can't post the diagram but I included the link.
ugh....I hate the math ones!!
I know this. The area of the Green is 682. The answer is 682
I found this gem...
If we know the length of each side of a pentagon, then the area of the pentagon is:
A = (1/4)a^2 * sqrt[25 + 10 * sqrt(5)]
where 'a' is the side length.
We can find the side length using the Law of Cosines.
Draw line segments from the center of the pentagon to two adjacent vertices. This forms an equilateral triangle where the two equal sides are 8 units long, and the length of the base is 'a'.
Since the pentagon is made up of five of these triangles, the central angle will be one-fifth of a complete circle.

Are you sure? How did you figure that out?

show us how you did it =O
i dont think 682 is right
we need work
I hate the math ones so I submitted 682..(I don't know either). My curiosity will probably make me figure it out later, but for now, that's what im going with. Thanks Heather. You saved me a lot of headache time.
I don't want to submit it if it is not right though, I submitted too early last week!
