Answer:
143.79
Step-by-step explanation:
The area of the figure can be found by splitting it into two shapes - a semi circle and a trapezoid.
The area of a semi-circle is found using A = 1/2πr² where r = 4.5 since the diameter is 9. A = 1/2π(4.5)² = 31.79.
The area of the trapezoid is found using A = 1/2(a+b)h = 1/2(23 + 9)(7) = 112.
Together the area is 31.79 + 112 = 143.79.
