Answer:
25.1 ft
Step-by-step explanation:
To solve for circumference is pretty simple. Just use the equation 2pi r (r=radius, radius is diameter divided by 2).
So essentially, apply to your calculator:
2(3.14)4=25.12
pretty simple! hope this helps!
Answer:
D
Step-by-step explanation:
First, find the coordinates of pointD if A(2,-6), B(10,2) and point D divides line segment AB in the ratio of 5:3.
If point D divides the segment AB in the ratio m:n, then

So

Point C has the x-coordinate the same as point A and the y-coordinate the same as point D.
Thus, C(2,-1)
First we have to isolate the varible
-2/5x-2=18
+2 +2
-2/5x=20
then divide both sides by -2/5 to get x completely by itself
-2/5x=20
------- ---
-2/5 -2/5
x=-50
i hope i've helped!
I believe the right answer is B!
