as the well is cylindrical in shape
so volume = π r² h
=π×(1.5)²×210 = 1485 m³
so cost = Rs 3×1485 = Rs 4455
so volume = π r² h
=π×(1.5)²×210 = 1485 m³
so cost = Rs 3×1485 = Rs 4455

volume of the tube well=πr²h
=>22/7*15/10*15/10*210
=>1485m³
therefore cost of sinking a tube well=1485*3
=> Rs.4455
=>22/7*15/10*15/10*210
=>1485m³
therefore cost of sinking a tube well=1485*3
=> Rs.4455
