Question

The inner diameter of a cylindrical vessel is 3.5 m. It is 100 m deep. Find the cost of polishing the inner curved surface area at the rate of Rs. 4 per m^2. (Use π = 22/7).



​

Answer 1

Answer:

Since we have given that

Diameter of cylindrical vessel = 3.5 m

Radius of cylindrical vessel =  

Height of cylindrical vessel = 100 m

So, Inner curved surface area would be

Cost per sq. m = Rs. 4

So, total cost of polishing would be

Hence, the cost of polishing would be Rs. 7700.
