about
2. In a right circular cone the axis is_to the diameter.
3. The difference between the C.S.A. and T.S.A. of a cone is​

Answer 1

Answer:

SO , YOUR ANSWERS :-

1) RIGHT - ANGLED TRIANGLE

2) PERPENDICULAR

3) C.S.A OF CONE =

$\pi rl$

T.S.A OF CONE =

$\pi rl \: + \pi {r}^{2}$

SO ,

$\pi rl \: + \pi {r}^{2} - \pi rl$

SO , BY SIMPLIFYING, WE GET ,

$\pi {r}^{2}$

[ANSWER] :- THE VALUE OF DIFFERENCE OF C.S.A. AND T.S.A. OF CONE IS

$\pi {r}^{2}$
