Answer: 4.02 c
Explanation:
so the area of a circle is equal to A=pi multiplied by the radius to the second power. And since that’s half a circle it would make sense for the area to be half of the full circle. The radius (half of the diameter and the area from the center of the circle to the outer edge.) is shown as 1.6ft, 1.6^2 is 2.56 and multiplied by pi that is 8.04 half of that is 4.02.
