The slant height and base diameter of a conical tomb are 25m and 14m respectively. Find the cost of white-washing its curved surface at the rate of Rs. 210 per `100\ m^2`

Explanation

given

`l=25m`

`r=14m`

so curved surface area`=pirl`

`=pixx14xx25`

`=1100m^2`

so the cost of white-washing its curved surface at the rate of Rs. 210 per 100 m^2`=(210xx1100)/100`

`=2310 rupees`
