Alenkinab [10]

Step-by-step explanation:

Arc length formula is

$s = rx$

where x is radinas.

A semi circle has a radian measure of

$\pi$

The radius is half of the diameter, 12 so the radius is

$12 \times \frac{1}{2} = 6$

So the arc length is

$6 \times \pi = 6\pi$

Area of semi circle is

$\frac{1}{2} \pi {r}^{2}$

where r is the radius.

$\frac{1}{2} \pi6 {}^{2}$

$\frac{1}{2} 36\pi$

$18\pi$
