Answer:6/8 pounds
Step-by-step explanation:
2 1/4 - 1 1/2
- 2 times 4 plus 1 = 9/4
- 1 times 2 plus 1 = 3/2
9/4 - 3/2
-to subtract your fraction, you need to have the same denominator in each side
- 4 times 2 = 8 (this is your denominator)
- 4 times 3 = 12 (your right numerator)
- 2 times 9 = 18 (your left numerator)
18/8 - 12/8 = 6/8

Answer:
for circle in circle: 75π
circle in square: 64-16π
note that answers are in exact form, since I don't know how the answer should be written (exact or decimal etc.)
Step-by-step explanation:
for circle in circle, we see that smaller circle (white circle) has radius 5 and big circle has radius 10. therefore we can find area of shaded area by doing
area of big - area of small
10²π - 5²π = 100π - 25π = 75π
circle in square, applying the same method, we can do square-circle
since the circle is inscribed in the square, the circle's diameter is 8, so its radius is 4
8²-4²π = 64-16π
