The equation for the area of a sector of a circle is expressed as the product of pi, square of the radius and the ratio of the angle of the sector and 360 degrees.

Area = πr^2 (α / 360°)

We obtain the angle by manipulating the equation.

α = (Area x 360°) / <span>πr^2 
</span>α = (2.512 cm^2 x 360°) / (π x 4^2)
<span>α =35.98</span>°

Can you guys please help me

There is an easy way to find y intercept. I can tell you how and show you the answer

1 {Y Intercept = 3 } [ This is where the line crosses the line going from up to down in the middle. ]

{slope = 2/1 } To find the slope you find a place where the slanted line is perfectly on the graph.:

You then go up. { GO UP FIRST! that will be the number on top. Stop when you notice the slanted line to the right is exactly on the graph. So what i did is started at (-1, 1) Then went up twice. I saw that to the right of me was the slanted line which was exactly on the graph. So I went up twice [2] then went right once [1]

To find your equation you just put y= [ y intercept form ] and your numbers you found.
y=2/1x + 3
Make sure you have x after your slope so you know it is always going up, no matter what number you put inside.

IF YOU WANT ME TO DO THEM ALL COMMENT. I WILL DO THEM ALL WITHOUT EXPLANATION.

** NOTE ** If the line is decreasing from the left. “\”it is negative so the slope will me - you will do that for your next question
