Answer:
A) y-4=-1/2(x+6)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-4)/(2-(-6))
m=-4/(2+6)
m=-4/8
simplify
m=-1/2
y-y1=m(x-x1)
y-4=-1/2(x-(-6))
y-4=-1/2(x+6)
We first need to find the radius of the circle, so we need to do 8π/π which gives us a diameter of 8 cm, halving this gives us a radius of 4 cm.
The area of this circle will be:
A = πr^2
A = 4^2
A = 16π cm^2
Now to find the volume we simply multiply the area by the height:
16π × 7 = 112π cm^3 which is our final answer.
When both increase, the slope is positive (+)/(+)=(+)
