From the worksheet, we can take pi as roughly 3.14

1.

l = 75/360 * 2pi *4

l = 5.23 cm (nearest hundredth)

2.

l = 130/360*10pi

I = 11.34cm (nearest hundredth)

3.

l = 75/360*2pi*6

l = 7.85cm

4.

l = 45/360*2pi*3

l = 2.36 cm (nearest hundredth)

5.

l = 80/360*1400pi

l = 976.89 cm (nearest hundredth)
