What is the area of each semicircle of the following composite figure? 12 ft x 4 ft rectangle and a 4 ft circle

12.56 ft 2

6.28 ft 2

50.24 ft 2

25.12 ft 2

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
