Aspherical balloon is inflating with helium at a rate of 8080piπ startfraction ft cubed over min endfraction ft3 min. how fast is the balloon's radius increasing at the instant the radius is 22 ft? write an equation relating the volume of a sphere, v, and the radius of the sphere, r.

=0.04132 ft/min

Step-by-step explanation:

V = volume of the sphere

r = radius of the sphere

= 80π ft³/min

now,

For sphere, V =

for rate of change of volume with respect to time (t)

or

or

at r = 22ft, = 80π ft³/min

80π =

or

=0.04132 ft/min
