Ineed ! i will mark brainliest, , and rate! . a circular window is surrounded by a circular frame. the radius of the window is z − 5 and the radius of the full circle formed by the frame is z + 5. write a polynomial that represents the area of just the frame itself, not including the space covered by the window.(the area of a circle is given by a = πr 2, where r represents the radius of the circle.) answer choices: -20 pi z 20 pi z 20 pi z+50 50
