<u>Answer</u>

B. Length = 37, width = 28


<u>Explanation</u>

Let the length of the rectangle be x,

width is 9 less. So, width = x - 9

Perimeter of a rectangle = 2(length + width)

2(length + width) = 130

2(x + x - 9) = 130

2(2x - 9) = 130

4x - 18 = 130

4x = 130 + 18

4x = 148

x = 148/4

  = 37

<em>Length = 37</em>

<em>Width = 37 - 9 = 28</em>

A circle has an area of 200.96 units2 and a circumference of 50.24 units. If the radius is 8 units, what can be said about the r
AleksandrR [38]

Answer:

C. The ratio of the area to the circumference is equal to half the radius.

Step-by-step explanation:

The area of a circle can be written as;

Area A = πr^2

The circumference of a circle is;

Circumference C = 2πr

Using the formula, w can derive the relationship between the two variables.

A = kC

k = A/C

Substituting the two formulas;

k = (πr^2)/(2πr) = r/2

So,

A = (r/2)C

A/C = r/2

The ratio of the area to the circumference is equal to half the radius.

Given;

Area = 200.96

Circumference = 50.24

Radius = 8

To confirm;

k = r/2 = 8/2 = 4

Also,

A/C = 200.96/50.24

A/C = 4
