Step-by-step explanation:
The formula of an area of a circle:
r - radius
The formula of a circumference of a circle:
We have the area of a circle
Substitute to the formula and solve for r:
<em>divide both sides by π</em>
Put the value of r to the formula of a circumference:
The correct answer is option B which is {x | x ≤ 4.5}
<h3>What is a number line?</h3>
A number line is a representation of a graduated straight line used to represent real numbers in introductory mathematics.
Because the arrow is pointing to the left, the answer to the solution set needs to be less than the number the dot is on.
A solid dot on a number means that that number is included in the solution set.
In the picture the solid dot is on 4.5, so the solution set needs to be equal to or less than 4.5.
Therefore the correct answer is option B which is {x | x ≤ 4.5}

A square can be classified as a rhombus, Square, Rectangle, quadrilateral, and parallelogram.
quadrilateral - 4 sides - 4 angles.
parallelogram - 2 pairs of parallel sides.
It is a rhombus - 4 congruent length sides and 2 pairs of parallel sides.
square- 4 sides- 4 congruent sides- 2 sets of parallel sides- 4 right angles
rectangle - 2 sets of parallel sides- 4 sides- 4 right angles- 2 different sets of congruent sides
*note* although a square can be a rectangle a rectangle can't be a square
