The volume of a closed cylinder of constant height 8cm is given by V=8(pi)r(squared). The radius of its base is 6cm and is increasing at the rate of 0.04cm/s
a) at what rate is the volume of the cylinder increasing? (to 2 decimal places)
b) at what rate is the total surface area of the cylinder increasing (to 2 decimal places)
I just need to verify my answers with someone quickly. thanx.
