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:
AAA
Step-by-step explanation:
Answer:
<h2>∠Q corresponds with ∠Z</h2>
Step-by-step explanation:
- form a graph
- draw Δ ZNM and ΔPQR on either side of the y- axis
- You reflect ΔZMN across the y- axis
- Then you translate said triangle up the graph
- The corresponding ∠'s will match and overlap.
- m∠Q ≅ m∠Z as well as being a corresponding triangle
