Answer:

Using the same Similar triangles property lets find the value of h, R/ r = (H+h)/ h. Therefore, the volume (V) of the frustum of the cone is =1/3 πH (R2 +Rr+r2 ).

 \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})  }
