curved surface area. of. Cone =πrl
where l is slant height
l²=r²+h²
so l²= 64+225=289
l=17 c.m
area = 3.14×8×17= 427.04cm²

CSA of right circular cone = πrl
l = √h² + r²
l =√15² + 8²
l = √225 + 64
l = √289= 17cm
CSA = πrl = πx 8 x 17 = 136π cm²
l = √h² + r²
l =√15² + 8²
l = √225 + 64
l = √289= 17cm
CSA = πrl = πx 8 x 17 = 136π cm²
