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:
2x° = 45°, 3x° = 67.5°
Step-by-step explanation:
Sum of angles in a triangle = 180°
2x+3x+3x=180°
8x=180°
x=22.5°
2x=22.5°x2=45°
3x=22.5°x3=67.5°
