Answer:
5cm
Step-by-step explanation:
volume = πr²h
225π = π × r² × 9
225/9 = r²
r = √225/9 = 15/3 = 5cm

Answer:
Therefore 20 degree is in First Quadrant,
i.e Quadrant I.
Step-by-step explanation:
QUADRANT:
When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.
Quadrant I - 0° to 90°
Quadrant II - 90° to 180°
Quadrant III - 180° to 270°
Quadrant IV - 270° to 360°
Therefore 20 degree is in First Quadrant, i.e Quadrant I.
When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.
Quadrant IV - 0° to -90°
Quadrant III - -90° to -180°
Quadrant II - -180° to -270°
Quadrant I - -270° to -360°
