just find h such that
π/3 (15/2)^2 * 12 = π*(10/2)^2 h
that is,
225π = 25π h
π/3 (15/2)^2 * 12 = π*(10/2)^2 h
that is,
225π = 25π h

Volume in funnel = (1/3)π(7.5^2)(12) cm^3
Assume the height in the cylinder will be h cm
Volume in cylinder = π(5^2)h cm^3
so
π(5^2)h = (1/3)π(7.5^2)(12)
25h = 4(56.25)
h = 225/25 = 9 cm

You find the area and not the volume
