I believe it’s c
Step-by-step explanation:
Answer:
h = 4cm
Step-by-step explanation:
Diameter = 18cm
Radius = Diameter/2 = 18/2 = 9cm
V = 1/3*pi*r^2*h
We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.
So,
108 pi = 1/3*pi*9^2*h
108 pi = (81pi*h)/3
multiply 3 from both side
108pi*3 = (81pi*h)/3 *3
324pi = 81pi*h
Now divide the 81pi from both side
324pi/81pi = (81pi*h)/81pi
4 = h
So the height is 4cm
Answer: C.) Congruent (or third option)
Answer:
Step-by-step explanation:
.
m is the slope of the line. To find it we can do 
which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So: 
. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant 
.
- Re-arranging to get b
Now re-write the equation as we have the constants.
26/8=3.25
14/4=3.5
You must show your work.
