Question

22) The diameter of two cones are equal .If their slant heights are in the ratio 5:4 .Find the ratio of their Curved surface area
Pls help me with this question....will mark brainliest​

Answer 1

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=5:4

The curved surface area of the two cones are πrl₁ and πrl₂.

So, the ratio of their curved surface area are πrl₁/πrl₂.

π and r are cancelled.

l₁/l₂=5/4

So, the ratio of the curved surface area of two cones is 5: 4

Answer 2

Step-by-step explanation:

since the diameters of two

Boiling is the process by which a liquid turns into a vapor when it is heated to its boiling point. The change from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the atmospheric pressure exerted on the liquid.
