Answer:
60º
Step-by-step explanation:
Label the radii OB and OC where AB and AC are tangents. OB and OC are 4.5 cm as they are both radii. Then we can see that OBA and OCA are both right triangles with OBA=OCA=90º. OAB=OAC=30º because the side lengths fit the criteria for a 30-60-90 triangle. OAB+OAC=60º

<h2>
THE CORRECT ANSWERS (B.)</h2>
Step-by-step explanation:
The answer of the larger circle = 254.34
Formula = radius*radius*π
The answer of the smaller circle = 113.04
254.34 - 113.04 = 141.3
