37 is your answer.

If u substitute in -4 for x, you will get -4^2 -3(-4) + 9.

-4^2 equals 16.

-3(-4) equals 12

16 + 12 = 28

28 + 9 = 37

Answer:

77.91 units²

77.91 square units

Step-by-step explanation:

the area of a circle is A=pi*r²

since we only need a certain fraction, we will multiply it with 62/360

62° is the given angle. 360° would be the full circle

A = pi * 12² * 62/360

note that the answer is in square units, bc in "r²" the units themselves get squared, even tough we don't know if its inch or kilometers, its definitely squared
