By the Chain Rule, we know that
I'm stuck on this problem: ( u = mu, since I don't know how to do the symbol)
"A spherical cell is growing at a constant rate of 400 um^3/day (1 um = 10^-6 m). At what rate is its radius increasing when the radius is 10 um?"
If someone could help me set this problem up, I'd appreciate it! Thanks!
