Answer:
not sure
Step-by-step explanation:
well, if we take the whole area of the circle, including the trapezoid in it, and then we <u>get the area of the trapezoid and subtract it from that of the circle's</u>, what's leftover is what we did not subtract, namely the shaded area. Let's notice the circle has a diameter of 20, thus a radius of half that, or 10.

Answer:
3 cups of flour.
Step-by-step explanation:
To solve this problem you would add 3 1/3 and 1 2/3 which would give you a total of 5. Then you would subtract 5 from you total 8 cups of flour which will give you a difference of 3 cups of flour left.
Its 17 15 and 8 i just did that on a test as well
srry no explanation :(
