volume of spheres practice find the volume of a sphere with a radius of nine CM
The formula to calculate the volume of a sphere is given by V = (4/3) * π * r^3, where r is the radius of the sphere.
In this case, the radius (r) is 9 cm. Therefore, substituting the values into the formula, we get:
V = (4/3) * π * (9 cm)^3
V = (4/3) * π * 729 cm^3
V ≈ 3053.63 cm^3
Hence, the volume of the sphere with a radius of 9 cm is approximately 3053.63 cm^3.
