Answer:
66.3 sq ft
Step-by-step explanation:
Here's the plan: we'll find the area of the circle then subtract the area of the triangle.
Area of circle:
A = pi•r^2
= pi•6^2
= 3.14•36
~= 113.04
Area of triangle:
A = 1/2bh
= 1/2(10.39)(9)
The height is the 6+3 in the image.
~= 46.755
Subtract to find
Area of Shaded:
113.04 - 46.755
= 66.285
Round to nearest tenth.
~= 66.3 sq ft
