hi dude!!

your answer...

given

  •        curved surface area of cone is 1884.4 m² = 188440 cm²

  •        slant height is 12cm

C.S.A = πrl

188440 = 3.14×r×12

by moving r towards LHS and others towards RHS.

r = 188440/3.14×12

r = 188440/37.68

r = 5001.0615 cm²

r = 5001 cm² approx.

hope it helps you.....
