Answer:
3054 cm³
Explanation:
recall that the volume of a sphere is given by
V = (4/3)πr³
where
r = radius
π = 3.14
We are given the diameter = 18 cm,
hence the radius = 18/2 = 9 cm
substituting this into the above equation,
V = (4/3)πr³
= (4/3)(3.14)(9³)
= 3053.63 cm³
= 3054 cm³ (to nearest cubic unit)
