To calculate the volume of a sphere, you can use the formula:
\[ V = \frac{4}{3} \pi r^3 \]
where \( V \) is the volume, \( \pi \) is approximately 3.14, and \( r \) is the radius of the sphere.
Given that the radius \( r = 2 \) cm, we can substitute it into the formula:
\[ V = \frac{4}{3} \times 3.14 \times (2)^3 \]
Calculating \( (2)^3 \):
\[ (2)^3 = 8 \]
Now substituting this back into the formula:
\[ V = \frac{4}{3} \times 3.14 \times 8 \]
Calculating \( \frac{4}{3} \times 8 \):
\[ \frac{4}{3} \times 8 = \frac{32}{3} \approx 10.67 \]
Now multiply by \( 3.14 \):
\[ V \approx 10.67 \times 3.14 \approx 33.4788 \]
Rounding to the nearest tenth:
\[ V \approx 33.5 \text{ cm}^3 \]
Thus, the volume of the sphere is 33.5 cm³.
