Complete the following table. (Take pi = (22)/(7))

Here are the solutions to the problems:

1. Complete the following table. (Take $\pi = \frac{22}{7}$)

• Row 1:
  • Given: Diameter $d = 14 \text{ mm}$
  • Radius $r = \frac{d}{2} = \frac{14 \text{ mm}}{2} = 7 \text{ mm}$
  • Circumference $C = \pi d = \frac{22}{7} \times 14 \text{ mm} = 44 \text{ mm}$
  • Area $A = \pi r^2 = \frac{22}{7} \times (7 \
