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)
