<h3>Given :-</h3>
<h3>To Find :-</h3>
<h3>Solution :-</h3>
The given function is ,
→ f(x) = -9x + 7 .
And we need to find out its value at x = 3 , that is f(3) . So just substitute x = 3 ,
→ f(3) = -9*3 +7
→ f(3) = -27+7
→ f(3) = -20

Answer:
41.8887 cm^2
Step-by-step explanation:
area of a circle
A = pi * r^2
A = pi * (3 + 4)^2
A = pi * 49
A = 153.94
120 / 360 = 1/3
153.94 / 3 = 51.3134
now area of inner circle
A = pi * 3^2
A = pi * 9
A = 28.274
28.274 / 3 = 9.4247
subtract
51.3134 - 9.4247 = 41.8887
