The volume of a sphere can be calculated using the formula:
V = (4/3) × π × r³
Where:
- V is the volume of the sphere.
- π (Pi) is approximately 3.14159.
- r is the radius of the sphere.
For a sphere with a radius (r) of 3 cm, we can plug that value into the formula:
V = (4/3) × π × (3 cm)³
Calculating (3 cm)³ gives us:
(3 cm)³ = 27 cm³
Now, substituting that back into the volume formula:
V = (4/3) × π × 27 cm³
V ≈ (4/3) × 3.14159 × 27 cm³
Calculating further:
V ≈ 113.097 cm³
Thus, the volume of a sphere with a radius of 3 cm is approximately 113.1 cm³.
