Answer:
360
Step-by-step explanation:
The exterior angles always add up to 360 in a polygon because it's the sum of all the vertexes which would make a circle.
Answer:
(f-g)(x) is given by -x^2+4x+6
Step-by-step explanation:
4.5 / 2 = 2.25cm radius for the smaller circle
3.14 (pi) × 2.25² = 15.89625cm²
10.5 / 2 = 5.25cm radius for the larger circle
3.14 × 5.25² = 86.54625cm²
86.54625 - 15.89625 = <span>70.65cm</span>²
The answer is 70.7cm².
