10

Answer 4

we know sqrt(110) is between
sqrt(100) and sqrt(121)
aka between 10 and 11, somewhere in the middle

Answer 5

So I'd go with 10.5

thank you. my last answer was 10.4 but it was wrong so I was thinking 10.5

it should actually be just a bit closer to 10.4, since it's not right in the middle.
