Explanation:

the volume of :

cone = ⅓π.r².r= ⅓π.r³

cylinder = π.r²r= π.r³

Sphere = 4/3 π.r³

for r = 9 in =>

the volume of:

14. cone = ⅓.π.9³= ⅓π × 729 = 243π in³

15. cylinder = π.9³ = 729π in³

16. Sphere = 4/3 π.9³ = 972π in³

17. the volume ratio among cone, cylinder and Sphere is : ⅓ : 1 : 4/3 =

1 : 3 : 4
