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.

Gemma had 25.75 grams of frosting
Used 15.5 grams
Left over:

Step-by-step explanation:
Let the number of blue marbles be x
number of yellow marbles = x/3
number of green = x- 90
ATQ
x + x/3 + x - 90 = 694
2x + x/3 = 784
(6x + x)/3 = 784
7x/3 = 784
x = 784 x 3/7
x = 112 x 3
x = 336
number of blue marbles = 336
