Answer: 5/51</h3>
======================================================
Explanation:
We have 6 green out of 6+6+6 = 18 total
The probability of getting green is 6/18 = 1/3.
After selecting that green jelly bean and not putting it back, we have 6-1 = 5 green out of 18-1 = 17 total.
The probability of selecting another green is 5/17.
Multiply the two fractions 1/3 and 5/17
(1/3)*(5/17) = (1*5)/(3*17) = 5/51
The probability of selecting two greens in a row is 5/51 where we do not put the first selection back. We also do not replace the green jelly bean with some other identical copy.
Note: 5/51 = 0.098039 approximately
The perimeter of a semicircle consists of two parts. (the curve and bottom)
That curve is half the distance around the circle, since it's been split in half.
The distance around a circle, the circumfrence, is equal to 2πr, where r is the radius of that circle. In this case, the circumfrence of the entire circle would be 16π. and so that curve would have a length of just 8π.
Using 3.14 for π, 8π = 8×3.14 = 25.12.
As for the flat part, that is the diameter (distance across) our circle.
The radius is the distance from the center of a circle to its edge, and always has half the length of the diameter. (you can break the diameter down into two radii)
If our radius is 8 meters, our diameter (the flat part of that semicircle) must be 16.
Now we add up the two parts of the perimeter...25.12 + 16 = 41.12.
