### surface area to volume ratio

the diameter of a worm is 2.4 cm and its length is 1.9 M.
a)work out the volume of the worm.
b)work out the surface area of the worm.
c)work out the surface area to volume ratio.

please can someone help me with these questions?
thanx kim xxx

Assume the worm is a cylinder. Calculate volume and surface. Surface to volume area ratio is Surface/volume using the same unit (meter or cm as you want, but be coherent).

Surface Area of a Cylinder = 2(pi)(r)² + 2(pi)(r)(h)
Volume of a Cylinder = (pi)(r)²h

pi = 3.14
h = 190 cm

I think the rest should be pretty basic, I've done most of the work for you, all u need to do is put it into a calculator.
