Answer: 46.90mins
Step-by-step explanation:
The given data:
The diameter of the balloon = 55 feet
The rate of increase of the radius of the balloon when inflated = 1.5 feet/min.
Solution:
dr/dt = 1.5 feet per minute = 1.5 ft/min
V = 4/3·π·r³
The maximum volume of the balloon
= 4/3 × 3.14 × 55³ 
= 696556.67 ft³
When the volume 2/3 the maximum volume
= 2/3 × 696556.67 ft³ 
= 464371.11 ft³
The radius, r₂ at the point is 
= 4/3·π·r₂³ 
= 464371.11 ft³
r₂³ = 464371.11 ft³ × 3/4 
= 348278.33 ft³
348278.333333
r₂ = ∛(348278.33 ft³) ≈ 70.36 ft
The time for the radius to increase to the above length = Length/(Rate of increase of length of the radius)
The time for the radius to increase to the
 above length 
Time taken for the radius to increase the length.
= is 70.369 ft/(1.5 ft/min) 
= 46.90 minutes
46.90mins is the time taken to inflate the balloon.

You're almost finished.
(sin/cos) times cos = 0
Look at the left side.  You could write it as (sin x cos) / cos = 0
and simply divide numerator and denominator by the cosine (cancel it).
Then what do you have left ? . . .  <u>sin(x) = 0</u>       Do I need to finish this for you ?
