The meaning of circumference is to find the distance around a circle or in other words the perimeter of the circle. The circumference of a circle can be calculate by using the formula
C=2πr or
C=πd, where r refers to the radius.
In this exercise is given a circle, which radius is 1 yard and it is asked to find its circumference and use 3.14 as the value of pi. In order to do that, you should substitute the given value of the radius and pi into the formula C=2πr.

The circumference of the circle is 6.28 yards.

Answer:The number of books that he had before last week is 28
Step-by-step explanation:
Let x represent the number of books that he had before last week.
Demetrious returned five library books last week. This means that the number of books left is x - 5
He returned three books this week. This means that the amount of books left is x - 5 - 3 = x - 8
He then checked out 8 more books. This means that the amount of books left is x-8-8 = x - 16
He now has 12 library books. This means that
x - 16 = 12
x = 12 + 16 = 28

Answer:
57.1°
Step-by-step explanation:
The sides of the rectangle are adjacent and opposite the angle, so the measure is ...
α = arctan(opposite/adjacent) = arctan(19.2/12.4) ≈ 57.1°
The angle between the diagonal and the short side is about 57.1°.
