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!
Answer:
( 1, 7.5 )
Step-by-step explanation:
First I found the midpoint of the G and H coordinates. Then I found the midpoint of that new coordinate and G.
3x - 50 = -20
Add 50 to both sides
3x = 30
x = 10
The number is 10

Step-by-step explanation:
Acceleration refers to the rate of change of speed with time. We can see that between 0 and 4.7 seconds he accelerated quickly . That means that the rate of change of speed with time was greatest between 0 and 4.7 seconds.
A graph of the motion is shown in the image attached. We can see that he maintained a constant speed after 4.7 seconds.
