Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
step 1
Find the circumference of the circle
The formula to calculate the circumference is equal to

we have

substitute

step 2
Find the approximate length of arc s
we know that
The circumference of a circle subtends a central angle of 360 degrees
so
using proportion
Find the arc length s for a central angle of 135 degrees

After selling 35 books, the store will break-even.
Step-by-step explanation:
Given,
Cost required per day to keep store open = $105
Amount spent on each book = $12
Let,
n be the number of books.
Total costs = 12n + 105
Selling price of each book = $15
Total revenue = 15n
For braking even;
Costs = Revenue

Dividing both sides by 3

After selling 35 books, the store will break-even.
