Answer:
4/5 is the answer in the simplest form
4.7, because its tenths place is highest
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.
In this exercise is given that diameter of a tire rim is 15 inches, and it is asked to find its circumference using 3.14 as the value of pi. In this problem the diameter of the circle is given, so in this case the formula
C=πd would be used, where
d represents the diameter.


The circumference of the tire rim is 47.1 inches.
<span>Option B. Arrange four-length sides so the diagonals are equal in length. Since a square is a rectangle with four equal sides the diagonals should bisect each other at each length and at 90 degrees to each other. This is really important. If the diagonals are equal in length and bisect each other at equal distance then the sandbox is measuring length and has equal angles which is a square by definition</span>
