If 2r=h+sqrt(r^(2)+h^(2)) the value of r:h is (r,h!=0)

The curved surfaec area (c) of a cone is pirl , where l=sqrt(r^(2)+h^(2)) , express h in terms of c and r.

If h is the height, I the slant height and r_(1), r_(2) radii of the circular bases of the frustum of a cone, then slant height of the frustum = sqrt(( r_(1) - r_(2))^(2) + h^(2)) . Find the height of the cone of which the frustum is a part = (h r_(1) /( r_(1) - r_(2) ).We have a bucket in the form of frustum of a cone in which h = 8 cm, r_(1) = 9 cm and r_(2) = 3 cm.
