To calculate the volume of a sphere, you can use the formula:

\[ V = \frac{4}{3} \pi r^3 \]

Where \( V \) is the volume and \( r \) is the radius of the sphere.

Given that the radius \( r = 3 \) cm and using \( \pi \approx 3.14 \):

  1. Calculate \( r^3 \): \[ r^3 = 3^3 = 27 \]

  2. Multiply by \( \pi \): \[ \pi r^3 = 3.14 \times 27 \approx 84.78 \]

  3. Multiply by \( \frac{4}{3} \): \[ V = \frac{4}{3} \times 84.78 \approx 113.04 \]

Rounding to the nearest tenth, the volume of the sphere is approximately 113.0 cm³.

Therefore, the correct response is: 113.0 cm³.
