total surface area of frustum of a cone = pie l(R+r) +pie(R^2+r^2)
where l= slant height of the frustum
h= vertical height
and R and r are radii of the two bases of frustum

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

 \implies \: tsa = \pi \: l(r1 + r2)

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