Will have a look at this by 4 am if no one has done them yeh
V = ⅓(h³ + 4h)
dV/dh = h² + 4/3
dh/dt = 2 (given)
dV/dt = dV/dh x dh/dt
= (h² + 4/3) x 2
= 2h² + 8/3
when h = 5,
dV/dt = 50+8/3
dV/dh = h² + 4/3
dh/dt = 2 (given)
dV/dt = dV/dh x dh/dt
= (h² + 4/3) x 2
= 2h² + 8/3
when h = 5,
dV/dt = 50+8/3
