Homework Statement
Separate variables and integrate to find an expression for r(t), given r0 at t=0
Homework Equations
M=ρ(4/3)πr3, thus V=(4/3)πr3
dM/dt=Cr3 where C is a constant
The Attempt at a Solution
∫dM=∫Cr3dt
M+constant=??
I have no idea how to integrate r because it's a function of t but we're not given the function. I don't think that integrating the left side this way will be very helpful either. Any advice would be much appreciated!
