Answer:
radius=2, height=3
Step-by-step explanation:
diameter= 2x the radius therefore 4/2=2=radius
cylinder volume formula=πr^2h
volume=12π
height= v/πr^2=12π/π*2^2=12π/π*2^2=12π/4π=3
hope this helped!
Answer:
(-1,0)
Step-by-step explanation:
Convert the equation to vertex form which becomes y=(x+1)^2+0
