Answer:
h=9m,r=18cm
l²=r²+h²
l²=18²+9² l=√324+81, l=√405,l=2•7(approx)
Curved Surface area of Cone=πrl
=22/7×18×2•7
u can solve this above multiplication u will get the answer in approximately

Answer:
1138.47m²
Step-by-step explanation:
l² = r² + h²
=> l² = 324 + 81
=> l = √405 = 9√5m
Cloth required = LSA of Cone = πrl
= (22/7)×18×9√5
= 3564√5/7
= 509.14√5
= 1138.47m²
