Answer 2

Step-by-step explanation:

slant height=13m

D = 24 m

r = d/2 = 24/2

12 m

C.S.A of cone = πrl

= 22/7×12×13

= 490.28m²

cost of white washing per 100 m² = Rs.240

cost of white washing per 1 m²=240/100

= Rs. 2.4

Cost of white washing= C.S.A of cone × cost per 1m²

=490.28×2.4

=Rs. 1176.67
