<h2>
At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.</h2>
Step-by-step explanation:
We have equation for volume of a sphere

where r is the radius
Differentiating with respect to time,

Given that
Radius, r = 24 cm

Substituting

At the moment when the radius is 24 centimeters, the volume is increasing at a rate of 2171.47 cm³/min.
