PHYS-100 QUIZ-I MAX. TIME : 35 min. Name___________________________ Rec. Sec. No.____________ _______________________________________________________________________ A = π r 2 ( θ /360); c = 2 π r ; A = ab/2 ; l = r θ ; a 2 +b 2 = h 2 Area of a trapezoid = h (b 1 +b 2 )/2 Note: Diagrams are not drawn to scale Prob.1 ( 10 pts). The shaded shape outlined in bold is cut out from a thin sheet of metal. Find the angle θ for R = 15.0 cm and r = 10.0 cm if the area of the figure is 344 cm 2 . The area of the figure is: ( π R 2 π R 2 θ 360 ) ( π r 2 π r 2 θ 360 ) = π ( R 2 r 2 )(1 θ 360 ) = 344 cm 2 Solving for θ we get: θ = 360 1 344 cm 2 π ( R 2 r 2 ) = 45

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
