What is interesting about the door that Enfield tells the story about? What did the door look like?

It was the only door and had no bell or knocker.

Explanation:

As the story begins we told a very ugly man was the only one who went in and came out through the old fashioned door.

The door according to Enfield was surrounded by "three windows". Another detail about it's appearance is that it was "blistered and distained".

the answer is

r ≈5.641

plug in the area of 100 yards into the equation

100=

divide each side by pi

≈ 31.8309=

take the square root of each side to find r

=r

r ≈5.641

showing or having an insensitive and cruel disregard for others. (so basically being heartless)

hope this : )
