Answer 3

A spherical balloon is inflated with gas at a rate of 600 cubic centimeters per minute.
(a) How fast is the radius of the balloon changing at the instant the radius is 30 centimeters
How fast is the radius of the balloon changing at the instant the radius is 80 centimeters

Answer 4

The total derivative of the sphere's volume expression\[V=\frac{4 \pi r^3}{3} \]is\[dV=4 \pi r^2 dr \]Plug in the numbers and solve for dr.
