Y-y1=m(x-x1)
find slope
(y2-y1)/(x2-x1)
so
(-4,-1)
(3,-3)
slope=(-3-(-1))/(3-(-4))=(-3+1)/(3+4)=-2/7
y-(-1)=-2/7(x-(-4))
y+1=-2/7(x+4)
Answer:
V ≈ 2144.70 
Step-by-step explanation:
Radius is going to be used instead of the diameter. Half of 16 is 8, and so that will be the value that shall be used.

V ≈ 2144.66 
V ≈ 2144.70

Step-by-step explanation:
Method:
Simultaneous equations
Explanation:
First we will need to get both equations to have the same subject, to do this we will multiply the bottom equation by 2.
1) 2a-3c=-6
2) a+2c=11 x2
Becomes
2) 2a+4c=22
Now we will make both equations equal to the same subject (2a)
1) 2a=3c-6
2) 2a=-4c+22
Because they are both equal to 2a, they are therefore equal to each other, so:
3c-6=-4c+22
7c=28
c=4
Now substitute c back into either equation to get a:
a+2c=11
a+2(4)=11
a=3
