What is the exact volume of a sphere with a diameter of 18 cm? ______ cm3
sashaice [31]


The formula for volume of a sphere is (4/3)πr², with r being the radius. Since the diameter of the sphere is 18 cm, the radius is 18/2, which is 9. Now substitute the 9 for r so you have:

V=(4/3)π*9²

V=(4/3)π*81

V=108π

108π is the exact volume of the sphere.
