10 is the estimate because you have 58, and you put it in 589 10 times.
First you need to find the area of the whole circle.

The radius is given as 10, so just insert 10 into the equation of the area of a circle equation.

Putting

after the 100 because that is what is commonly done.
Because the circle is then being split into 4 equal sections, we need to find 1/4 of the area of the whole circle to find the area of one of these sections.
Since the area of the whole circle is

then we just divide that by 4,
leaving us with 25

and that is our final answer
<u>Answer</u><u>:</u>
1/2,3/5,5/8,7/11,9/14,11/17
<u>Explanation</u><u>:</u>
Each time, the numerator of the fraction goes up by 2 and the denominator goes up by 3.
In an hour there are 60 minutes.
6:38 PM + 22minutes = 7 PM
From 7 PM to 7:23 PM there are 23 minutes
So, (23 + 22) minutes = 45 minutes.
4 loaves : 6 cups
That simplifies to 2 loaves : 3 cups
So, your ratio is 2:3
