The paper cup would not roll straight. One end was 7cm in diameter, and the other end was 5 cm in diameter. In one roll of the cup, how far would the larger end roll? Use 3.14 for pie

• Math -

What you are doing here is comparing the circumference , the distance which is rolled

bottom of cup: radius = 5 cm, so the circumference is
2πr = 10π
top of cup: radius = 7 cm, so the circumference is
14π or appr 43.96 cm
