4+2+8+6 = 20 total
8 purple
so 8/20 reduced to 2/5 chance for a purple
then there will be 19 left
6 blue =
6/19 probability of having a blue one
2/5 * 6/16 = 12/80 reduces to 3/20 probability total

Answer:
Hello,
Just using the theorem of Thalès,
Step-by-step explanation:
Let say h the hight of the building
The answer:
the calculus of the circumference depends on what is the value of central angle, so we can take for example 120° the value of the central angle.
<span>since the length of arc ab is 28.61, and the central angle is 120°, we can find the circumference simply by using the following formula:
ARC = Radius x Angle, so Radius = ARC / Angle = 28 .61 / 120° = 0.23 unit
the circumference of a circle is C = 2 x radius x Pie
</span>C = 2 x radius x Pie = 2 x 0.23 x 3.14 = 1.49 unit
