Answer:
Volume of Cone = 24mm³
Volume of Cylinder = 72mm³
Step-by-step explanation:
Area of circle ( the shaded area ) for cone and cylinder is 18mm³
To find the radius:
We know Area of circle = πr²=18mm²
r²= 18/π
Volume of Cone =1/3πr²h=(1/3)π×18/π×4=24mm³
Volume of Cylinder=πr²h=π×18/π×4=72mm³
Therefore Volume of Cylinder=3× Volume of Cone
Second option is correct.
