Given,
h is 9 cm..
Also, base circumference = 44
2*π*r is 44
So, r = 7 cm...
Volume of cone is 1/3 * π* r^2 * h
= 1/3 * 22/7 * 49 * 9
= 154 * 3
= 462 cm^3...
Hope this helps, Merry Xmas......

Answer:
461.81
Step-by-step explanation:
volume of cone = 1/3 *base area *height
circumference = 2πr
44cm = 2*22/7*r
44cm/2*22/7 = r
7 = r
putting r in formula of volume
volume = 1/3 * πr² *h
=1/3 * 22/7 * 7 *7 *9
=461.81
