Answer:
The arc length of the semicircle is: , which is approximately 34.5575
Step-by-step explanation:
Recall that the length of a circumference of radius R is given by:
therefore, the arc length of a semicircle (half of the circle) would be given by half of the previous expression:
So, in our particular case of radius 11, the formula for the arc length of the semicircle becomes:
Hello!
The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.
First, let's find the y-intercept. This is where the line hits the y-axis. Therefore, it hits at 4 on the y-axis, so our y-intercept is 4.
To find the slope, let's find 2 points on our line. Let's use (0,4) and (2,5). We divide the difference in the y-values by the difference in the x-values as shown below.
Therefore, our slope is 2.
Now we plug these values into our equation.
y=2x+4
I hope this helps!
