**helper**, Friday, January 14, 2011 at 3:26pmArea K = 1/2 r^2 * angle in rads

Convert deg to rads

125 deg * pi/180 = 25pi/36 rads

K = 1/2 * 3^2 * 25pi/36

K = ? m^2

you do the math

Area K is expressed in m^2 (in this case)

**Bosnian**, Saturday, January 15, 2011 at 12:45amArea of circle:

A=r^2*pi

Area of your sector=r^2*pi*(125/360)=3^2*pi*125/360=9*pi*125/360

=9*3.1415926535*125/360

=3534,2917351875/360

=9,8174770421875 m^2
