Answer:

hi Zara

Step-by-step explanation:

Total cost of point=2200Rs.

cost of point/m2=20Rs.

depth of vessel=10m

 Inner curved surface area painted=cost/m2totalcost=202200=110m2

 Now, 2πrh=110m22×722×r×10=110r=2×22×10110×7=1.75m

∴ radius of the base is 1.75m.

 capacity of vessel=πr2h=722×1.75×1.75×10=96.25m3

hope it will help you
