A square side is twice of the radius
sq side: 4 x 2
sq side: 8
find the area of the square.
A = b x h
A = (8) x (8)
A = 64
<em>Area of square is 64</em>
----------------------------------------------------------------------------------------------------------------
Find the area of the circle
Area of circle:
A = πr²
A = π(4)²
A = 16π
A = 16(3.14)
A = 50.24
----------------------------------------------------------------------------------------------------------------
Divide the circle from the total
50.24/64
50.24/64 = 0.785
0.785 = 78.5/100 = 78.5%
----------------------------------------------------------------------------------------------------------------
Subtract the circle's percentage from 100% (the total)
100 - 78.5 = 21.5
21.5% is your chance of not hitting a point in the circle.
-----------------------------------------------------------------------------------------------------------------
21.5%, or (B), is your answer

Answer:
3500
Step-by-step explanation:
I divided everything and I ended up just multiplying 70x50 which got me 3500. I'm sorry, but I don't know in what way to write the equation. I don't know if it's y=mx+b or some other way. all I was able to come up with was y=50x+70
S=2pieRh
To solve for R you have to get it by itself.
R=S/2pieh

Answer:
Angle HAB and Angle FAE are congruent angles
Step-by-step explanation:
we know that
Two angles are supplementary if their sum is equal to 180 degrees
In this problem
m∠FAH+m∠HAB=180° ----> by a linear pair
Remember that
A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. A linear pair of angles must add up to 180 degrees
m∠FAH+m∠FAE=180° ----> by a linear pair
therefore
m∠HAB=m∠FAE -----> by vertical angles
Angle HAB and Angle FAE are congruent angles
