Answer:
The answer to your question is 34.24 mm²
Explanation:
Data
diameter = 8 mm
height = 4 mm
Process
1.- Calculate the area of the triangle
Area = (1/2)(base x height)
Area = (1/2)(8 x 4)
Area = (1/2)(32)
Area = 16 mm²
2.- Calculate the area of the circle
Area = πr²
Area = (3.14)(4)²
Area = 50.24 mm²
3.- Calculate the area of the shaded area
Area = 50.24 - 16
Area = 34.24 mm²
