find the area of the shaded regions below. give your answer as a completely simplified exact value in terms of π (no approximations)

Step-by-step explanation:

the area of the hemisphere is  1/2

the radius is 1/2 the diameter,

the diameter is also the hypotenuse of the isosceles triangle

= +

= 32

d =

r = 1/2

1/2(1/2)^2

1/2(1/4*32)

(32/8 )*

4 ( the entire upper hemisphere )

area of the triangle is  1/2* 4 *4 = 8

then the exact area of the parts of the circle would be

4 - 8
