Question

the slant height and base diameter of a conical tomb are 25m and 14m respectively . find the cost of white washing its curved suraface at the rate of ₹12per m sq

Answer 1

We will first have to find it's curved surface area to get the cost
Curved surface area of cone =πrh
Curved surface area of conical tomb = 22/7*7*25
=550m^2
Cost of washing = 12*550
= Rs.6600
Hence,the cost of washing the curved surface of conical tomb is Rs.6600
