Heya !!!
Slant height of Frustum of cone = 5 cm
And,
Difference between their radii = 4 cm
we know that,
(Slant height)² = (H)² + (R-r)²
(5)² = (H)² + (4)²
25 = (H)² + 16
(H)² = 25 - 16
H = ✓9 = 3 cm

we suppose slant height is l.
l=5 cm
l²=(h)²-(r1-r)²
h²=(5)^2-(4)^2
h²=9
h= root 9=3 cm
hope it helps ^_^
