Question

a closed cylindrical tank is 3 m deep and its base radius is 63cm if the tank is made by steel find the cost of steel used to make the tank at 185 rupees per m square​

Answer 1

Answer:

Rs 2659.3380

Step-by-step explanation:

r=0.63m

deep/h=3m

Total Surface Area =2*22/7*0.63*363

=44*9*363m^2

=14.3748m^2

1m^2=Rs185

143748m^2=Rs185*143748

=Rs2659.3380

Answer 2

Answer:

surface area = 2πrh+2πr²

=2x22/7x0.63x3+2x22/7x0.63²

11.8692+2.4925

14.3617m²

cost=185x14.37

2658.45 rs
