the tank has the capacity of 6160 m^3 and the radius is 14m
imagine the depth is h m
so the volume of the tank is π×14×14×h m^3
According to the question,
π×14×14×h=6160
or, 22/7 ×14×14×h=6160
or, 22×14×2×h=6160
or, h=10m
so the surface area is =π×14(2×10 + 14)m^2
= 44×34 m^2=1496 m^2
so the total cost will be =(1496×30)₹ = 44880 ₹
