Answer:
72πcm³/s
Step-by-step explanation:
Volume of the spherical balloon V = 4/3πr³
dV/dr = 4πr²
The rate at which the volume of the balloon increasing is expressed as;
dV/dt = dV/dr • dr/dt
dV/dt = 4πr² • (2)
Given
Radius r = 3cm
dV/dt = 4π(3)² • (2)
dV/dt = 36π×2
dV/dt = 72πcm³/s
Hence the rate at which the volume is increasing is 72πcm³/s
