Match the terms (1.1.1 to 1.1.5) with the correct definitions (A to I) from TABLE 1.

1.1 Diameter

The diameter $d$ of a circle is twice the radius $r$.

$d = 2r$

Substitute $r = 12$ cm:

$d = 2 \times 12~cm = 24~\mathrm{cm}$

$\boxed{24~cm}$

1.2 Area

The area $A$ of a circle is given by $A = \pi r^{2}$.

$A = \pi r^{2}$

Substitute $r = 12$ cm:

$A = \pi (12~cm)^{2} = \pi \times 144~cm^{2} = 144\pi~cm^{2}$

$\boxed{144\pi~cm^{2}}$

1.3 Radius

The radius is given as $r = 12$ cm.

$\boxed{12~cm}$
