The slant height and base diameter of a conical tomb are 25 m and 14 m respectively. Find the cost of white-washing its curved surface at the rate of Rs 210 per 100 .
Diameter of the base of a conical tomb m
Radius of the base of a conical tomb m
Slant height of the conical tomb m
Curved Surface Area of the conical tomb
Cost of white washing 100 of curved surface area = Rs 210
Cost of white washing 1 of curved surface area =Rs Rs 2.1
Therefore, cost of white washing 550 of curved surface area Rs 1155
