Answer:
(16π - 32) in²
Step-by-step explanation:
In the picture attached, the circle is shown.
Area of one-quarter of circle = 1/4*Area of a circle = 1/4*π*radius² = 1/4*π*8² = 16π in²
Area of the triangle = 1/2*base*height = 1/2*8*8 = 32 in²
Shaded area = Area of one-quarter of circle - Area of the triangle = (16π - 32) in²
