If the radius is 12in, find the area of the shaded sector of the circle

25.13? or something close to that?

Step-by-step explanation:

120 is 1/3 of 360, so I did the area of the circle as a whole and divided THAT by 3, but I'm not 100% sure if it's right.. let me know if so!

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
