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.

A= y*z- w*(z-x)=10*5-5*(5-3)=50-5*2=50-10=40 in.^2
B is the answer
First factor the equation
(x-10)(x+2) = 0
Then solve for (x-10) and (x+2)
x=10
x=-2
Answer:
15
Step-by-step explanation:
63 - 18 = 45 ( Minus the number of cakes that are left over)
45 / 3 = 15 (Divide by 3 to find out how many cakes they sold each day)
" 35% " means " 0.35 ".
" of " in math almost always means " times ".
So the problem is: (0.35) x (60)
You can easily do that with a pencil or a calculator.
