Answer:
C 68.4 cm²
Step-by-step explanation:
The area of the semicircle is given by ...
A = 1/2π(d/2)^2 = (π/8)d^2
A = (π/8)(9 cm)^2 ≈ 31.8 cm^2
The area of the trapezoid is given by ...
A = 1/2(b1 +b2)h
A = 1/2(9 cm + 5 cm)(4 cm) = 28 cm^2
Then the total area is ...
31.8 cm^2 +28 cm^2 = 59.8 cm^2
Of the offered choices, 68.4 cm^2 is closest.
