-- XY is a "diameter" of the circle.
-- A diameter is any straight line inside the circle that goes
through the center and touches the curvy part twice.
-- Every diameter of the same circle has the same length.
-- The distance around every circle is (its diameter) multiplied by (pi).
-- Half of the diameter is called the "radius" of the circle.
A radius is any straight line inside the circle that goes between
the center and the curvy part.
-- The area of every circle is (its radius, squared) times (pi).
-- 'Pi' ( π ) is a number. It's a decimal that keeps going forever
and never ends, so you can never write it exactly with numbers.
-- Pi is roughly 3.14 , and if you use 3.14 whenever you need pi,
then your answers will be about 0.05% too small.
That's very close. When you turn in an answer that's only
0.05% wrong, the teacher knows that you know how to solve
the problem, and that's way more important than the answer.
For the circle in your picture, the diameter is 17in, the radius
is 8.5in, and the area must be (pi) (8.5)² square inches.
You can go ahead and work that out.

Answer: 110
Step-by-step explanation:
We first need to find the maximum perimeter of the circular area rug that will fit in the rectangular space. We use the shortest side of the rectangle as the diameter of the rug.
A circle drawn inside a rectangle.
A rectangle has a length of 12 feet and a height of 7 feet. A circle is drawn inside in the center of the rectangle with a line labeled Diameter extending from the top most point of the circle to the bottom most point of the circle.
P=2πr=2π×72=21.9911 ft
We then multiply the perimeter of the rug by the cost per foot.
cost =21.9911×5=$109.9555
Rounded to the nearest whole number, the cost of the maximum circumference circular rug that can fit in the dining room is 110 dollars.
