Answer:

radius 12 units = 452.16 units²

diameter 16.8 units = 221.5584 units²

stiks02 [169]

Answer:

x = 6

Step-by-step explanation:

The probability that this archer hits her first shot is given by t the probability of being windy and that she hits the shot added to the probability of not being windy and that she hits the shot:

P(H_{first}) = P(H_w)*P(W)+P(H_{nw})*(1-P(W))\\P(H_{first})=0.4*0.3+0.7*(1-0.3)\\P(H_{first})=0.12+0.49 = 0.61

If the probability that she hits the target on her first shot is 0.x1, the value of x is:

P(H_{first})=0.61=0.x1\\x=6

1.Use the diagram of the regular hexagon to support an explanation showing why the formula accurately yields the area of the hex
alekssr [168]
Even though im not giving you the whole answer, let me give you something that will definitely help you:
a regular hexagon is made of 6 identical triangles with the apothem as the height of the triangle A = 6 * 1/2 base * apothem which can be simplified to A = 1/2 perimeter * apothem
This in itself is a big part of what you need. I hope this is enough info for you to keep going
