There are four parts of a circle, so you have to find out the area of the circle:-
10 cm=Radius
=100
=3.14
3.14*100=314 
Now, find the area of the square box:-
Since half the side of the square is 10 cm, the total length of one side is 2*10 which is 20 cm.
Area=S*S
=20*20=400 
Now subtract the area of the box from the area of the square:-
400-314= 86
That is the area of the shaded part.
Happy to help you!
I assume the equation is

then let
.


The right side is real-valued and positive, and only on the left side do we have an imaginary term, which tells us

Then




but again we omit the negative solution, so that

Answer:
Step-by-step explanation:
A rotation of -90 degrees about the origin is equivalent to a clockwise rotation. Point A, initially at (2, 0), would become point A', (0, -2).
Answer:
7
Step-by-step explanation:
Simplify the following:
13 (-5) - 8 (-9)
13 (-5) = -65:
-65 - 8 (-9)
-8 (-9) = 72:
-65 + 72
-65 + 72 = 7:
Answer: 7
A circle is a fixed distance from all other points on the circle
