total surface area of vessel=curved surface area of hemisphere+curved surface area of cylinder
= 2πr square +2πrh
=2.22/7.7.7+ 2. 22/7. 7. 6
=44/7 + 44.6
iske a age fraction me lekr solve kr Lena . yahaan possible ni he solve kr na

Answer : 572cm2
Step-by-step explanation:
Diameter = 14cm
Radius=14/2
=7cm.
Height of the cylinder= 13-7
= 6cm
Now,inner surface area of the vessel=csa of cylinder +csa of hemisphere
2(pie)rh+2(pie)r^2h
84(pie)+98(pie)
182(pie)
182.22/7
26.22
572 cm^2..............
