Answer» wer: The slant HEIGHT of the cone is 12 cm. Step-by-step explanation: GIVEN that:The volume and curved surface area of a cone are same. The product of RADIUS and height of the cone is 36 cm. To Find:The slant height of the cone. Finding the slant height of the cone: Volume of a cone = Curved surface area of a cone ⟶ (πr²h)/3 = πrl ⟶ πr²h = 3πrl Cancelling π and r both sides. ⟶ rh = 3l ⟶ 36 = 3l [Given] ⟶ L = 36/3 ⟶ l = 12 ∴ The slant height of the cone = 12 cm |
