Answer:

1:7

Step-by-step explanation:

We can look at this like simplifying fractions. The fraction would be 4/28, and all we need to do is find the highest number that both the numbers are equally divisible by. In this case, that number is 4. 4/4=1 and 28/4=7 so the new fraction is 1/7. Then we replace the division sign with : to signify a ratio, thus getting 1:7.

Answer:

percentage of the total capacity is 75.6%

Step-by-step explanation:

Hello! To solve this problem we follow the following steps

1. draw the complete scheme of the problem (see attached image)

2. To solve this problem we must find the area of the circular sector using the following equation.(c in the second attached image)

$A=\frac{R^2}{2} (\alpha -sin\alpha )$

$\alpha =2arccos(\frac{d}{R})$

3. observing the attached images we replace the values in the equations and find the area of the circular sector, remember that you must transform the angle to radians

$\alpha =2arccos(\frac{5}{7})=88.83$
