**Jai**, Monday, April 4, 2011 at 10:54pmto do this, we calculate both of the circles' circumference. the bigger circle has diameter of 26 in, while the smaller has diameter of 18 in.

now recall that the circumference of a circle is given by

C = 2*π*r

or given the diameter,

C = π*d

where

π = constant equal to 3.14

r = radius

d = diameter

substituting,

bigger circle:

C = π*d = 3.14*26 = 81.64 in

smaller circle:

C = π*d = 3.14*18 = 56.52 in

then we subtract:

81.64 - 56.52 =

25.12 in

hope this helps~ :)
