Joshua and Isabella are having a snowball fight. Joshua has a snowball, shaped as a sphere, with a radius of 6 cm. Isabella also has spherical snowball with a radius of 3 cm. Find the volume of each snowball (use 3.14 for ). Then, complete the following statement, and round the answer to the nearest hundredth, if necessary.

1 answer

To find the volume of each snowball, we will use the formula for the volume of a sphere, which is given by:

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

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

Volume of Joshua's Snowball

Joshua's snowball has a radius of \( 6 \) cm:

\[ V = \frac{4}{3} \times 3.14 \times (6)^3 \]

Calculating \( (6)^3 = 216 \):

\[ V = \frac{4}{3} \times 3.14 \times 216 \]

Now, calculating \( \frac{4}{3} \times 3.14 \):

\[ \frac{4}{3} \times 3.14 \approx 4.1867 \]

Now, we can calculate:

\[ V \approx 4.1867 \times 216 \approx 903.8372 \]

Rounding to the nearest hundredth:

\[ V \approx 903.84 \text{ cm}^3 \]

Volume of Isabella's Snowball

Isabella's snowball has a radius of \( 3 \) cm:

\[ V = \frac{4}{3} \times 3.14 \times (3)^3 \]

Calculating \( (3)^3 = 27 \):

\[ V = \frac{4}{3} \times 3.14 \times 27 \]

Calculating \( \frac{4}{3} \times 3.14 \):

\[ \frac{4}{3} \times 3.14 \approx 4.1867 \]

Now, we can calculate:

\[ V \approx 4.1867 \times 27 \approx 112.99 \]

Rounding to the nearest hundredth:

\[ V \approx 112.99 \text{ cm}^3 \]

Complete the Statement

Joshua's snowball has a volume of 903.84 cm³, while Isabella's snowball has a volume of 112.99 cm³.
