Question

Diameter of two right circular cone are equal if there is length height are in the ratio 3 is to 2 then what is the ratio of their curved surface area

Answer 1

CSA of 1st cone ÷ CSA of 2nd cone 
πr1l÷πr2l
(since radius and value of π were equal they would get devided with 1 as remainder)
I.e, ration would be
l÷l
I.e, 3 ratio 2
