Okay, so if your rectangle is 16 by 8, that means that the circle diameter of 8 because that would be outside of the card's width,
the area of the rectangle is 16 x 8 or 128
the radius of the circle would be 4 (because 1/2 of the diameter is radius)
we know that the equation of the circle PIr^2, so the area of the circle is 16PI
then, the remaining area would be calculated by 128-16PI
This comes out to be approximately 77.73
Well if you write out all the possibilities, it would look like this:
AAB
ABB
ABA
BBA
BAB
BAA
^ That is just assuming that you can't do BBB & AAA.
With that, the probability of getting ABA is 1/6 because there are 6 possibilities that the code could be but you are only looking for 1 of those.
Now if you can use BBB & AAA, it would be 1/8.
Answer:
2 × 1 +2 × 4= 10
Step-by-step explanation:
because 2×1 is 2 and 2×4 is 8 then you add them and get 10
