Answer:
mark me brainlist plz...........
Step-by-step explanation:
The diameter of the hemispherical bowl is 12cm
The radius of the hemisphere r=
12÷2=6cm
The curved surface area of the bowl=2πr
=2×3.14×6×6
=226.08cm ²
The total height of the vessel is =16 cm
The height of the cylindrical part=16−6
=10cm
The surface area of the cylinder =2πrh
=2×3.14×6×10
=376.8cm ²
The surface area of the vessel=surface area of the cylinder+surface area of the sphere
=377.14+226.28
=602.88cm ²
