Question

How to find TSA OF a CONE WHEN DIAMTER IS GIVEN PLZ DO NOT APPLY THE CASUAL FORMULA to find TSA of a CONE i need new formula based on diameter this time is given do not convert diameter to radius and DO NOT apply old formula of Tsa OF CONE . I need new formula based on direct diameter based .did you understand my question plz students of brainly fast in a sheet of paper only also show me the deravation how you got the new formula in a paper only ​

Answer 1

Hey bro....

The question is very interesting.

✓The actual formula for TSA will not change.

✓The diameter needs to be inserted in the old TSA formula of a cone.

The new formula derived by me is:

$( \frac{(\pi.d(2l \: + \: d))}{4})$

d is the diameter .

L is the slant height.

✓However if L is not provided,

by old formula, L = √{(r^2)+(h^2)} =

[√{(d^2)+(h^2)}]\4.

✓assuming [...] as K, L = K/4

2L = K/2

✓The formula becomes [π.d.{K+2d}]\8

Hope this helps you.
