Answer:
⅕
Step-by-step explanation:
Ate ⅓, so 1 - ⅓ = ⅔ left
⅔ of 8 = ⅔ × 8 = 16/3
Ate ⅖, so 1 - ⅖ = ⅗ left
⅗ of 16/3 = ⅗ × 16/3 = 16/5 = 3⅕
Ate 3 more, so
3⅕ - 3 = ⅕ left

Answer:
<h2>
36.48 mm^2</h2>
Step-by-step explanation:
The area formula of a circle is:
A=pi*r^2
a semicircle is half the area of a circle:
A=0.5*pi*r^2
now lets find that area:
A=0.5*pi*r^2
A=0.5*pi*8^2
A=0.5*pi*64
A=<u>32pi </u>mm^2
A= around 32*3.14
A= around 100.48 mm^2
Now, lets find the area of the triangle:
it is half the product of the diameter and radius:
A=0.5*8*(8+8)
A=4*16
A=64 mm^2
Now lets find the approximate area of the shaded region:
Asc-At=Ashaded
Ashaded=100.48-64
Ashaded=36.48 mm^2
