Answer:
<u>Each of the 4 sectors have an area:</u>
- πR²/8 - πr²/8, where
- R = 28/2 - 2 = 12 in
- r = 6/2 = 3 in
<u>Find the area:</u>
- A = π/8(12² - 3² ≈ 53 in²
<u>Outer perimeter of the frame:</u>
- P = d + πd/2 =28( 1 + π/2) ≈ 72 in
4.99 /2 = 2.495
9.85/6 =1.641666666
The 6 oz is a better deal
Answer:
Ming must add 0.375 L of a 10% sugar solution
Step-by-step explanation:
if 3 L = 80%
1.5 L should = 40% (since it is half of 80%)
and if 40 divided by 4 = 10%
1.5 also needs to be divided by 4
so 1.5 divided by 4 = 0.375
that means Ming must add 0.375 L of a 10% sugar solution
