volume:ration

A worm has a diameter of 2.4cm and its length is upto 1.9M.
a)How do I calculate the surface area?
b)How do I calculate the volume?
c)How do I work out the volume ratio of the worm?
Please help!
Thanx kim xxx

Surface area= PI*2*radius * length]
Volume= PI * radius^2 * length

volume ratio = volume/area
