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
8 is in the hundreds place
1 is in the tens place
7 is in ones or units place
D.
Where (h, k) is the center of the circle and the radius is squared.

6^2 + 12 - 3^2
36+12-9
