2019 F = ma Exam A — Question 10

A flat uniform disk of radius 2R has a hole of radius R removed from the center. The resulting annulus is then cut in half along the diameter. The remaining shape has mass M. What is the moment of inertia of this shape, about the axis of rotational symmetry of the original disk? 45 — Source: Question 10, 2019 F = ma Exam A, © 2019 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
