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
Answer:
176 square yards
Step-by-step explanation:
<u><em>The picture of the question in the attached figure N 1</em></u>
we know that
The area of the walkway around the rectangular pool, is equal to the area of two trapezoids (#1 and #2), plus the area of two smaller rectangles (#3 and #4)
see the attached figure N 2 to better understand the problem
step 1
Find the area of the two trapezoids (#1 and #2)
![A=2[\frac{1}{2}(b_1+b_2)h]](https://tex.z-dn.net/?f=A%3D2%5B%5Cfrac%7B1%7D%7B2%7D%28b_1%2Bb_2%29h%5D)
simplify

we have

substitute

step 2
Find the area of the two smaller rectangles (#3 and #4)
![A=2[LW]](https://tex.z-dn.net/?f=A%3D2%5BLW%5D)
we have

substitute
![A=2[(4)(6)]=48\ yd^2](https://tex.z-dn.net/?f=A%3D2%5B%284%29%286%29%5D%3D48%5C%20yd%5E2)
step 3
Find the area of the walkway around the rectangular pool
