Answer:
10.89
Step-by-step explanation:
Circle:
C = TTD
C = TT(6.6)
C = 20.73451151
C = 20.73
Triangle:
A = bh/2
A = 6.6(3.3)/2 6.6/2=3.3
A = 21.78/2
A = 10.89
Shaded Region = 10.89
Let, the number = x
Then, 2(x + 10) = -20
2x + 20 = -20
2x = -20 - 20
x = -40/2
x = -20
In short, The number would be: -20
Hope this helps!
