To find the volume of a sphere, we use the formula:

$V = \frac{4}{3} \pi r^3$

Where:

• $V$ is the volume,
• $r$ is the radius, which is half of the diameter.

Given that the diameter is 43.5 cm, we can calculate the radius as:

$r = \frac{43.5}{2} = 21.75 \text{ cm}$

Now, substituting the radius into the formula for volume:

$V = \frac{4}{3} \pi (21.75)^3$

Let's calculate this.

$V = \frac{4}{3} \times 3.1416 \times (21.75)^3 \approx 43058.5 \text{ cubic centimeters}$

Rounding to the nearest tenth, the volume is approximately:

$V \approx 43058.5 \text{ cm}^3$
