The volume V=³ of a spherical balloon changes with the radius.

Question 3 of 20

a. At what rate (ft³/ft) does the volume change with respect to the radius when r = 3 ft?

b. Using the rate from part a, by approximately how much does the volume increase when the radius changes from 3 to 3.1 ft?

a. At what rate (ft3/ft) does the volume change with respect to the radius when r = 3 ft?

ft³/ft

(Type an exact answer in terms of t.)

C---

b. Using the rate from part a, by approximately how much does the volume increase when the radius changes from 3 to 3.1 ft?

ft³

(Use the answer from part a to find this answer. Round to two decimal places as needed.)
