Help me with this topic pls

Answer 1

Answer:
The cylinder is 72 mm2

Step-by-step explanation:
Volume for shapes that have the same bottom and top = Base x Height

Answer 2

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.
