The diameter is 14 mm.

The circumference in terms of Pi is 14 Pi mm.

Using StartFraction 22 over 7 EndFraction  for Pi, the approximate value of the circumference is 44.0 mm.

The parallelogram whose diagonals are equal in length and not perpendicular is
mamaluj [8]

Answer:

Rectangle.

Step-by-step explanation:

If the diagonals are equal then the parallelogram is a rectangle. They are also equal in length in a square, which can be regarded as a special type of rectangle - but in this case the diagonals are perpendicular. They are also perpendicular in a rhombus.

A rectangles width is one-fourth of its length . its area is 9 square units
Paha777 [63]

Answer:

Length = 6

Width = 3/2

Step-by-step explanation:

You can choose to go about this question in lots of different ways, but this is how i did it. I drew a diagram of the rectangle and labeled it: the height/length as x and the width as x/4 (they told us the width is a quarter of the length). They also told us that the area is 9 square units.

We know that length x width = area

So: length x width = 9

I'm gonna bring in the variables i used in the diagram, so:

x x \frac{x}{4} = 9

Keep solving:

\frac{x^{2} }{4}= 9

Times both sides by 4:

x^{2} = 36

Square root both sides for x:

<em>* remember that when you square root, its possible to have a positive or negative version of the value</em>

x = ±6

Since its impossible to have a negative length, we can say that x = 6.

X was just the variable we gave to the length of the rectangle, so now we know the length is 6. If you needed to find width as well, you can do 6/4, which simplifies to 3/2.

To double-check

- 6 x 3/2 should equal 9, since length x width = area

which it is, so we're correct!

Hope that helped : )
