Diameter of the cylinder = 7 cm

Therefore, Radius of the cylinder

Total height of the solid = 19 cm

Therefore, Height of the cylindrical portion= 19 - 7

= 12 cm

(1 mark)

Therefore,

Volume of the solid = Volume of the cylindrical portion + Volume of the two hemispherical ends

= Total surface area of the solid = Curved surface area of the cylinder + Curved surface area of two hemispherical ends

= 22 19

= 418 cm²

mark as brain list please
