Answer:
8+pi/2
Step-by-step explanation:
The area of the rectangle on the bottom is 8, or 2*4. The area of the top is half (because it's a semi circle) of pi*r^2, or just 1/2 pi
Unsure of what you mean by "reference number."
I do recognize that 11pi/9 is in quadrant III. I suspect that the so-called "reference number" is the acute angle between the end ray of 11pi/9 and pi, or, in more easily comparable numbers, between 9pi/9 and 11pi/9.
That difference is 2pi/9.
I don’t really know what you mean here but i guess you mean f(x)=2x+3=0
In that case:
F(x)=2x+3=0
Subtract 3 from both sides:
F(x)=2x=-3
Divide both sides by 2:
F(x)=x=-3/2.
