The wheel of an adult's bicycle has diameter 26 in. The wheel of a child's bicycle has diameter 18 in. To the nearest inch, how much farther does the larger bicycle wheel travel in one revolution than the smaller bicycle wheel?

to 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~ :)

the endpoints of a diameter of a circle are A(2,1) and B(5,5). Find the area of the circle in terms of pie.
