The slant height and base diameter of a ...

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\ m^2`.

Text Solution

Verified by Experts

Curved Surface Area of the conical tomb is
`CSA=pirl`
`CSA=22/7xx7xx25=550m^2`
Cost of white washing the tomb at Rs. 210 per `100m^2` is
`bb"Cost"=210/100xx550= Rs. 1155`
