Answer 1

Answer: hi mate here is ur answer

frustrum: a portion of a cone which remains after cutting of the conical part of the cone on the top.

$\Large\mathcal\green{FRUSTUM}$

$\implies \: tsa = \pi \: l(r1 + r2) + \pi \: {r1}^{2} + \pi {r2}^{2}$

$\implies \: csa = \pi \: l(r1 + r2)$

$\implies volume = \frac{1}{3}\pi \: h( {r1}^{2} + r1.r2 + {r2}^{2} )$

$\implies slant \: hieght = \sqrt{h - ( {r1}^{2} + {r2}^{2}) }$
