Question
A spherical balloon is being inflated such that its
radius is increasing at a rate of 2 cm per second. After 5 seconds, find the volume of the balloon. (Use π = 3.14)Solution
Radius after 5 seconds = 2 × 5 = 10 cm Volume of sphere = (4/3)πr³ = (4/3) × 3.14 × (10)³ = (4/3) × 3.14 × 1000 = 4186.6 cm³.
