Acircle with area 81ㅠ has a sector with a central angle of 120°.

what is the area of the sector?

either enter an exact answer in terms ofㅠ or use 3.14 forㅠ and enter your answer as a decimal.

84.78

Step-by-step explanation:

We have the area of a circle

The sector with a central angle of

Calculate, what part of 360° is an angle 120°:

The same part of an area of a circle is an area of a segment.

Therefore:

Use π ≈ 3.14

The answer is

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
