Answer 1

steps

Let the depth of the tank be x

Given:-

Volume of tank =6160m³

Radius of tank =14m

As we know that, volume of tank is given as-

V=πr²h

Therefore,

Volume of tank =πr²h

⇒ 22/7×(14)²h=6160

⇒616h=6160

⇒h= 616/6160m

⇒h=10m

Hence the depth of the tank is 10m

curved surface area of tank

=2×22/7×14×10=880m²

Given that the cost of painting is Rs.3 per m² Therefore,

Cost of painting the curved outer surface of tank =3×880=Rs.2640

Hence the cost of painting the curved outer surface is Rs.2640.
