heya,,.
lateral surface Area of the frustum of cone is
=πl(R+r), where l=h^2+(R-r)^2.
R*is Big radius of cone
and r is small radius of cone .
now,
total surface area of frustum cone =πR^2+πr^2+πl(R+r)
we can also write it,...
total surface area of frustum of cone is
π(R^2+r^2+l(R+r)sq unit
.
hope it help you
