Diameter of two cones are equal if their heights are in 7 ratio 4 find ratio of their c.s.a |
| Answer» Since the diameters of two cones are equal, their radius will also be the same.Let the slant height of the two cones be l₁ and l₂ respectively.Therefore,l₁ : l₂ = 7 : 4The curved surface area of the two cones are\xa0πrl₁ and πrl₂So, the ratio of their curved surface area are\xa0πrl₁/πrl₂\xa0π and r are cancelled.⇒\xa0l₁/l₂\xa0= 7/4So, the ratio of the curved surface area of two cones is 7 : 4 | |
