Answer:
What kind of question is it?
We know that
area of circle =pi*r²
for r=4 ft
area=pi*4²------> 16*pi ft²
<span>the shaded sector of the circle represent 3/4 of the total area
so
3/4*16*pi-----> 12*pi ft</span>²
the answer is
12*pi ft²
You just have to add the three
4/8+3/8+1/8=8/8
8/8=100%
So they finished the whole project
Hope this helps!
