The formula for the volume of a sphere is V = (4/3)πr^3.

Substituting r = 9 cm into the formula, we get:

V = (4/3)π(9^3)
= (4/3)π(729)
= 972π cm^3

So the volume of the sphere is 972π cm^3.

The formula for the volume of a sphere is V = (4/3)πr^3.

Substituting r = 3 m and π ≈ 3.14 into the formula, we get:

V = (4/3)(3.14)(3^3)
= (4/3)(3.14)(27)
= 113.04 m^3

So the volume of the sphere is approximately 113.04 m^3.

The formula for the volume of a sphere is V = (4/3)πr^3, where r is the radius.

The radius of the sphere is half of the diameter, so r = 12/2 = 6 m.

Substituting r = 6 m into the formula, we get:

V = (4/3)π(6^3)
= (4/3)π(216)
= 288π m^3

So the volume of the sphere is 288π m^3.

The formula for the volume of a sphere is V = (4/3)πr^3, where r is the radius.

Substituting r = 12 mm and π ≈ 3.14 into the formula, we get:

V = (4/3)(3.14)(12^3)
≈ (4/3)(3.14)(1728)
≈ 2880.64 mm^3

Rounded to the nearest hundredth, the volume of the chocolate truffle is approximately 2880.64 mm^3.
