Here is the required answer:-
Circumference= 236 cm
2πr= 236 cm
πr= 118 cm
r= 118/π cm
Now Curved Surface Area of cone=πrl=π×118/π×12=118×12=1416 cm².
Hope this helps you...

Hi there !!
Given :
Circumference of the base = 2πr = 236 cm
2×22/7× r = 236
r = [236×7] ÷ [ 2 × 22 ]
r = 37.54 cm [ approx.]
Slant height = l = 12 cm
C.S.A = πrl = 22/7 × 37.54 × 12
= 1415.79 cm² = 1416 cm² [ approx.]
