To find the volume \( V \) of a sphere, you can use the formula:
\[ V = \frac{4}{3} \pi r^3 \]
where \( r \) is the radius of the sphere.
Given that the radius \( r = 9 \) cm and using \( \pi \approx 3.14 \):
- Calculate \( r^3 \):
\[ r^3 = 9^3 = 729 \]
- Now plug this value into the volume formula:
\[ V = \frac{4}{3} \times 3.14 \times 729 \]
- First, calculate \( \frac{4}{3} \times 3.14 \):
\[ \frac{4}{3} \times 3.14 \approx 4.18667 \]
- Now multiply this by \( 729 \):
\[ V \approx 4.18667 \times 729 \approx 3053.63 \text{ cm}^3 \]
Rounding this to two decimal places gives:
\[ V \approx 3052.08 \text{ cm}^3 \]
So the volume of the sphere is approximately:
\[ \boxed{3052.08 \text{ cm}^3} \]
