Was always free? I have always kept this question in my mind. The site says, "To support your homeschooling, you have unlimited answers for the time being."

It is free actually but you can ask unlimited questions always. But you can't search up as many questions, there was a limit of 10. Now since this virus it has changed and is free for people who are still in school which would be us homeschoolers.

So to answer you no it didn't always use to be free. You can still get premium but for now it's free.

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
