Given
Capacity of cylinder (volume) =6160cm³
Radius =14cm
Volume of cylinder= pi r² h
Pi r² h =6160
22/7 x 14 ² x h =6160
H=6160x7/14²x22
H=10cm
Curved surface area of cylinder = 2 pi r h
=2 x22/7 x 14 x10
=2x22x2x10
=880cm²
Cost of painting 1cm²=₹3
Cost of painting 880cm²=880x3
=₹2640
This is ur ans hope it will help you in case of any doubt comment below
