A cylindrical vessel, without lid, has to be tin-coated on its both sides. If the radius of the base is 70 cm and its height is 1.4 m, calculate the cost of tin-coating at the rate of Rs. 3.50 per 1000 cm 2 .

Question

Philoid · Accepted Answer

Given,

Radius of base = 70 cm

Height of base = 1.4 m = 140 cm

So,

Area =

Tin coating must be done on both side so Area =

∴ Cost of tin coating at rate Rs.3.50 per 1000 cm² =
