I need help pls
Suppose you know the area of a circle and the measure of the central angle of a sector. Describe the process of finding the area of the sector.

Divide the measure of the central angle by (Drop-Down Menu Choices: 180,90,360) and multiply the result by the (Drop-Down Menu Choices: Area, Circumference, Radius) of the circle.

360

radius crrt me if im wrong

Step-by-step explanation:

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
