Answer:

14π or 43.98

Step-by-step explanation:

Area of the whole semi-circle is about 21π

Divide 42 into thirds and 1/3 is the diameter of the small semi-circle (14 in) now the area of the small semi circle is: 7π

The area of the shaded region is 14π or about 43.98

(this may be slightly off because I actually used π)
