Question

B. The slant height and base diameter of a conical tent are 25 m and
14 m respectively. Find the cost of white washing its curved surface
at the rate of 210 per 100 m2​

Answer 1

Answer:

Curved surface area of a cone =πrl, where r is the radius of the cone and l is the slant height.

-

Radius of the tomb = Diameter/2=7m

Hence, CSA of this conical tomb ,

22/7×7×25=550 sq. m.

Cost of white washing the tomb at Rs. 210 per 100m

=

210/100 ×550= Rs. 1155
