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 \( r \) is 7 cm, we can substitute this value into the formula:
\[ V = \frac{4}{3} \times 3.14 \times (7)^3 \]
First, calculate \( 7^3 \):
\[ 7^3 = 7 \times 7 \times 7 = 343 \]
Now substitute this back into the volume formula:
\[ V = \frac{4}{3} \times 3.14 \times 343 \]
Now, calculate \( 4 \times 3.14 \):
\[ 4 \times 3.14 = 12.56 \]
Now, multiply this by 343:
\[ 12.56 \times 343 \approx 4307.08 \]
Now divide this by 3:
\[ \frac{4307.08}{3} \approx 1435.69 \]
Rounding this to the nearest hundredth gives:
\[ 1435.69 \text{ cm}^3 \]
Therefore, the volume of the sphere is approximately 1,436.03 cm³.
So the correct answer is:
1,436.03 cm³
1,436.03 cm cubed
