$\Large\fbox{\color{purple}{ SOLUTION }}$

$\Large\mathcal\pink{FRUSTUM}$

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

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

Answer 2

Answer:

 

<font color= "Red"> Frustum</p><p>Curved Surface Area = π(r 1 + r 2 )l.</p><p>Total Surface Area =π(r 1 + r 2 )l + πr 1 2 + πr 2 2</p><p>Volume = 1/3 πh (r 1 2 + r 2 2 + r 1 r 2 )
