Lower bound is 17.6 and upper bound is 17.8
9.4
It is: 21.2

17.2
Well, friend, when we talk about the lower bound of a number, we're looking at the smallest possible value it could be. So, for 19.4 corrected to 1 decimal place, the lower bound would be 19.3. Remember, it's all about paying attention to those little details and finding the beauty in each number!
The correct answer is 20.0
13.2 percent (rounded to 1dp).
Circumference of a circle is equal to pi*diameter, or 2*pi*radius, so if d=17.4cm, c=54.7cm (to 1dp), if r=17.4cm, c=109.3cm (to 1dp).
The radius is 3.45
