Answer 2

Answer:

$A=77.04\ in^2$

Step-by-step explanation:

we know that

The area of the shaded sections is equal to the area of the circle minus the area of the triangle

so

$A=\pi r^{2} -\frac{1}{2}(b)(h)$

where

$r=12/2=6\ in$ ----> the radius is half the diameter

$b=12\ in\\h=6\ in$

substitute

$A=(3.14)6^{2} -\frac{1}{2}(12)(6)$

$A=77.04\ in^2$
