Find the areas of the shaded regions.
1 answer:
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
