Purpose of use
Calculate the surface area of a segment of a urinary catheter
Comment/Request
The formula for calculating the final surface area is wrong. It should be S = F + pi(r1^2 - r2^2) NOT S = F + 2pi(r1^2 - r2^2) becasue the surface area of a circle is pi*r^2, not 2pi*r^2
from Keisan
The hollow cylinder has a top surface and a bottom surface. (pi*r^2 * 2)
